alsa_sound: prevent lowlatency errors triggering WD reset

- HAL tries to recover from pcm write or read failure
  by closing and reopening pcm driver.
- There is no check when pcm is reopened. If the
  reopen fails it keeps trying multiple times in loop
- Fix the issue by checking error condition and
  return on failure.
