ALSA: sb: Deletion of unnecessary checks before two function calls
The functions release_and_free_resource() and snd_util_memhdr_free() test
whether their argument is NULL and then return immediately.
Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
