hal: Ensure that stream is not started during Sub system restart.

-out_write is suppose to simulate the write to hardware
and drop the data during SSR (non compress offload usecases),
and the time taken up by out_write should be equal to time
required to render the same data.
-Current implementation ends up calling start_output_stream,
where as part of error handling out_write sleeps for 50ms.
- Hence the total time taken by out_write during SSR exceeds the
total buffer duration by almost 2 times, this results in
incorrect update of timeStamp values in the player.
-Ensure that out_write/in_read returns without starting a stream
during SSR.
-During SSR, return correct number of frames written to HAL
in case of non compress offload sessions.
