ALSA: sis7019: Fix the missing error handling 

The previous cleanup with devres forgot to replace the snd_card_free()
call with the devm version.  Moreover, it still needs the manual call
of snd_card_free() at the probe error path, otherwise the reverse
order of the releases may happen.  This patch addresses those issues.

Fixes: 499ddc1639 ("ALSA: sis7019: Allocate resources with device-managed APIs")
