15)frameworks/base: Fix for FM over A2DP issue.

- When trying to play FM over A2DP, it fails to play.

track creation returns error and issue is seen.
Here, for BT stack  minFrameCount value is higher
compared to frameCount passed and fails.
-Increase the frameCount value in writerthread
of FMA2DPWriter.
