Merge "When switching surface, do not set mSeekNotificationSent as true, because there could be a previous uncompleted seeking which needs to send back MEDIA_SEEK_COMPLETE message. If we set mSeekNotificationSent as true here, then mediaplayer.cpp will be waiting for message MEDIA_SEEK_COMPLETE. The getCurrentPosition() will always return the seek time before MEDIA_SEEK_COMPLETE being received by mediaplayer.cpp. Fix for bug 5181272."
