Takashi Iwai f3d233daf0 ALSA: pcm: Relax __free() variable declarations 
We used to have a variable declaration with __free() initialized with
NULL.  This was to keep the old coding style rule, but recently it's
relaxed and rather recommends to follow the new rule to declare in
place of use for __free() -- which avoids potential deadlocks or UAFs
with nested cleanups.

Although the current code has no bug, per se, let's follow the new
standard and move the declaration to the place of assignment (or
directly assign the allocated result) instead of NULL initializations.

Fixes: ae92139848 ("ALSA: pcm: Use automatic cleanup of kfree()")
