msm: audio: qdsp6v2:  Check return code from audio_aio_open()

When audio_aio_open() is triggered in blocking fashion, it  frees audio
resouces and returns error code. In the current implementation,  callers
did not check the error code which can lead to dereference to freed
resources and cause system crash.  Update the callers to check return
code and then return error back to application to avoid the issue. In
the meanwhile, update the audio_aio_open not to free memory for caller
and leave the caller to free the memory in error condition.

msm: audio: qdsp6v2: Fix for kernel crash during stability

- Userspace calling AYSN_READ during flush, READ_DONE ack for
  this is coming after FLUSH_DONE which is hitting BUG_ON as
  buffers are removed from in_queue/out_queue during flush.
- Fix is to avoid sending READ requests to DSP until flush
  is complete.
