[FM] FM recording can not be stopped in notification bar

Select "Start Recording" in options menu -> Press "Home"
key, drag-down notification bar -> Tap "stop recording"
button -> Check the screen, "Save recording?"dialog will
not pop up.

The fix is set different intent actions to distinguish
which intent is called at onNewIntent(). If clicking stop
button, need to stop recording.
