audio:sst:error handling during stream alloc

audio:sst:error handling during stream alloc

BZ: 32085

In rarest cases, the previous stream free may not freed by
firmware.  In such error conditions, firmware will not be
able to do stream alloc and returns stream in use error.
This causes no audio activity in a device until reboot.

If stream alloc fails due to stream in use error, free it
immediately and return the error to application.  Application
would retry again and will succeed in audio playback or capture.
