Finally I got an answer to your's and my problem .Issue is you need to specify actions (mMediaSessionCompat.setActions(PlaybackStateCompat.ACTION_PLAY_PAUSE) even while updating mediasession. So your code should now look like

  private void updateMediaSessionMetaData() {
     int playState = mPlaying
            ? PlaybackStateCompat.STATE_PLAYING
            : PlaybackStateCompat.STATE_PAUSED;
           mMediaSessionCompat.setMetadata(new MediaMetadataCompat.Builder()
                .putString(MediaMetadata.METADATA_KEY_ARTIST, getArtist())
                .putString(MediaMetadata.METADATA_KEY_ALBUM, getAlbum())
                .putString(MediaMetadata.METADATA_KEY_TITLE, getSongTitle())
                .putLong(MediaMetadata.METADATA_KEY_DURATION, duration())
                .putLong(MediaMetadata.METADATA_KEY_TRACK_NUMBER, mSongPosn)
                .putLong(MediaMetadata.METADATA_KEY_NUM_TRACKS, songs.size())
                .putBitmap(MediaMetadata.METADATA_KEY_ALBUM_ART, albumArt)
                .build());
mMediaSessionCompat.setPlaybackState(new PlaybackStateCompat.Builder()
                .setState(playState, position(), 1.0f)
                .setActions(PlaybackStateCompat.ACTION_PLAY_PAUSE| PlaybackStateCompat.ACTION_SKIP_TO_NEXT|PlaybackStateCompat.ACTION_SKIP_TO_PREVIOUS).build()); 

UPDATE : Added code for MediaCallback & Receiver

   private final class MediaSessionCallback extends MediaSessionCompat.Callback {

    @Override
    public void onPlay() {
        pausePlayer();
    }
    @Override
    public void onPause() {
        pausePlayer();
    }
    public void onSeekTo(long pos) {
        seek(pos);
    }
    @Override
    public void onSkipToNext() {
        playNext();
    }
    @Override
    public void onSkipToPrevious() {
        playPrev();
    }
}

Receiver :

 public class MusicIntentReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {

        if (intent.getAction().equals(
                android.media.AudioManager.ACTION_AUDIO_BECOMING_NOISY)) {

            Intent intent1 = new Intent(MusicService.ACTION_PAUSE);
            intent1.setClass(context,
                    com.xyz.service.MusicService.class);
            // send an intent to our MusicService to telling it to pause the
            // audio
            context.startService(intent1);

        } else if (intent.getAction().equals(Intent.ACTION_MEDIA_BUTTON)) {

            KeyEvent keyEvent = (KeyEvent) intent.getExtras().get(
                    Intent.EXTRA_KEY_EVENT);
            if (keyEvent.getAction() != KeyEvent.ACTION_DOWN)
                return;

            switch (keyEvent.getKeyCode()) {
                case KeyEvent.KEYCODE_HEADSETHOOK:
                case KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE:
                    Intent intentToggle = new Intent(
                            MusicService.ACTION_TOGGLE_PLAYBACK);
                    intentToggle.setClass(context,
                            com.xyz.service.MusicService.class);
                    context.startService(intentToggle);
                    break;
                case KeyEvent.KEYCODE_MEDIA_PLAY:
                    Intent intentPlay = new Intent(MusicService.ACTION_PLAY);
                    intentPlay.setClass(context,
                            com.xyz.service.MusicService.class);
                    context.startService(intentPlay);

                    break;
                case KeyEvent.KEYCODE_MEDIA_PAUSE:
                    Intent intentPause = new Intent(MusicService.ACTION_PAUSE);
                    intentPause.setClass(context,
                            com.xyz.service.MusicService.class);
                    context.startService(intentPause);

                    break;
                case KeyEvent.KEYCODE_MEDIA_NEXT:
                    Intent intentNext = new Intent(MusicService.ACTION_NEXT);
                    intentNext.setClass(context,
                            com.xyz.service.MusicService.class);
                    context.startService(intentNext);

                    break;
                case KeyEvent.KEYCODE_MEDIA_PREVIOUS:
                    Intent intentPrev = new Intent(MusicService.ACTION_PREV);
                    intentPrev.setClass(context,
                            com.xyz.service.MusicService.class);
                    context.startService(intentPrev);

                    break;
                default:
                    break;
            }
        }
    }
