ALSA: pcm: Use automatic cleanup of kfree()
There are common patterns where a temporary buffer is allocated and
freed at the exit, and those can be simplified with the recent cleanup
mechanism via __free(kfree).
A caveat is that some allocations are memdup_user() and they return an
error pointer instead of NULL. Those need special cares and the value
has to be cleared with no_free_ptr() at the allocation error path.
Other than that, the conversions are straightforward.
No functional changes, only code refactoring.
