Do not handle MOD_SHUTDOWN equally to MOD_UNLOAD in sound kernel module.
MOD_SHUTDOWN is not an end of existence, and there is a life after it.
In particular, code previously called on MOD_SHUTDOWN grabbed lock and
deallocated unit numbering. That caused infinite wait loop if snd_uaudio
tried to destroy its PCM device after that point.

MFC after:	3 days
