[PATCH] remove redundant NULL checks before kfree() in sound/ and avoid casting pointers about to be kfree()'ed

Browse Source 
Checking a pointer for NULL before calling kfree() on it is redundant,
kfree() deals with NULL pointers just fine.
This patch removes such checks from sound/

This patch also makes another, but closely related, change.
It avoids casting pointers about to be kfree()'ed.
