ALSA: core: Make snd_card_free_when_closed() return void
All callers from other files ignore the return value of this function.
And it can only ever return a non-zero value if the parameter card is NULL.
This cannot happen in snd_card_free() as card was dereferenced just before
snd_card_free_when_closed() is called. So the error handling can be dropped
there.
