    I done it by declaring global js variable as false

    var isFirstGoogle = 0;

    Then to check this variable

    if(isFirstGoogle)
{
//wont enter here first time
}
isFirstGoogle = 1;

    So next time when I click on button the above method will be called as now isFirstGoogle = 1;

    Hope this help!! It's a temporary thing I know but it's working for me.

    Best solution is to render sign-in button only when user is not signed in. 

    <html>
<head>
   <meta name="google-signin-client_id" content="YOUR_CLIENT_ID">
</head>
<body>
  <script>
    function onSignIn(googleUser) {
      var profile = googleUser.getBasicProfile();
      var user_name = profile.getName();
      alert(user_name);
    }

    function onLoad() {
      gapi.load('auth2,signin2', function() {
        var auth2 = gapi.auth2.init();
        auth2.then(function() {
          // Current values
          var isSignedIn = auth2.isSignedIn.get();
          var currentUser = auth2.currentUser.get();

          if (!isSignedIn) {
            // Rendering g-signin2 button.
            gapi.signin2.render('google-signin-button', {
              'onsuccess': 'onSignIn'  
            });
          }
        });
      });
    }
  </script>

  <div id="google-signin-button"></div>

  <script src="https://apis.google.com/js/platform.js?onload=onLoad" async defer></script>
</body>
</html>
