AudioFlinger: flush direct tracks that are paused
Normally the flush is processed on ObtainBuffer.
But that is not called when the track is paused.
So it was not possible to flush and re-prime a
track that was paused.
Now we flush synchronously for inactive tracks,
and flush from prepareTracks_l for active tracks.
