Okay, so I researched this in great detail, and stumbled upon this helpful article online:

http://www.c2itconsulting.com/2013/10/ios-flash-setting-on-camera-picker-only-available-after-view-is-displayed/

I took their advice, and now I set the flash setting just before the user takes the picture. Instead of checking to see what the camera's current flash setting is, all I do is check my flash button's titleLabel text to see what the user wants as their flash setting:

Here is the code I came up with, which solves the problem perfectly for me now. I hope this helps out all of you with this same problem that didn't exist on iOS 7.0, but now does on iOS 7.1.

#define deviceHasCameraFlash [UIImagePickerController isFlashAvailableForCameraDevice:UIImagePickerControllerCameraDeviceRear]

- (void)capturePhoto
{
    if (self.cameraDevice != UIImagePickerControllerCameraDeviceFront && deviceHasCameraFlash)
    {
        if ([self.flashButton.titleLabel.text isEqualToString:@"Auto"])
        {
            self.cameraFlashMode = UIImagePickerControllerCameraFlashModeAuto;
        }
        else if ([self.flashButton.titleLabel.text isEqualToString:@"Off"])
        {
            self.cameraFlashMode = UIImagePickerControllerCameraFlashModeOff;
        }
        else if ([self.flashButton.titleLabel.text isEqualToString:@"On"])
        {
            self.cameraFlashMode = UIImagePickerControllerCameraFlashModeOn;
        }
    }

   [self takePicture];
}
