frameworks/av: Fix ANR during voice call recording when call ends

- While doing voice call recording, when the call ends ANR observed
- When the call is disconnected, audio HAL receives -1 from driver and
  audio HAL propagates this error to AudioFlinger.  But AudioFlinger
  is not sending error status to audio source to stop recording.
  Because of this audiorecord thread keeps on waiting for buffers
  which is resulting in ANR.
- To avoid indefinite wait, a timeout of 1 sec is set for buffer
  in audioSource and after timeout, -ETIMEDOUT is returned
  to recorder thread.
