ALSA: Fix uninintialized error return
Static analysis with cppcheck found the following error:
[sound/core/init.c:118]: (error) Uninitialized variable: err
..this was introduced by commit 2471b6c80a70e80de69f5ff4c37187c3912e5874
("ALSA: info: Register proc entries recursively, too") where the call
to snd_info_card_register was removed and no longer setting the error
return in err. When snd_info_create_card_entry fails to allocate a
an entry, the error path exits with garbage in err. Fix is to return
-ENOMEM if entry fails to be allocated.
Fixes: 2471b6c80a ("ALSA: info: Register proc entries recursively, too")
