Takashi Iwai 1d0eb6143c ALSA: ymfpci: Fix the missing snd_card_free() call at probe error 
Like a few other drivers, YMFPCI driver needs to clean up with
snd_card_free() call at an error path of the probe; otherwise the
other devres resources are released before the card and it results in
the UAF.

This patch uses the helper for handling the probe error gracefully.
