hardware/alsa_sound: Add NULL check for pcm handle in recover code

- Mediaserver crash is observed in pcm stream close
- The recovery code doesnt check if handle is invalid before trying
  to close the stream. Last read or write call may be blocked on
  acquiring lock and by the time it acquires lock the pcm stream
  might be closed. This results in calling pcm stream close on a
  NULL handle
- Fix this problem by adding a NULL check for pcm handle before pcm
  stream close in read and write recovery code

hardware/qcom/audio: Misc fixes for LPA/Tunnel

- Add support for Mono clips.
- Fix the issue for short clips or end of duration
- Prevent flush after EOS is completed as this will put
  DSP in bad state
- Acquire mParent's mLock before closing device to prevent
  concurrency issues with other streams.
- Device switch is crashing because of empty set parameter
  implementation. Implement setparameter to allow proper routing.
