audio:Avoid AudioTrackThread if Track creation fails

-mAudioTrackThread is starting before the track creation.
 This thread is used to process the audio buffer, which
 is no longer valid if the track creation itself is
 failing.

-Fix is to check for the result of track creation and
 based on the result need to start the mAudioTrackThread.
