ALSA: remove unnecessary null check
This function is only called from snd_ctl_ioctl() and the file parameter
can never be null so there is no need to check it here.
We dereference file at the start of the function:
struct snd_card *card = file->card;
and it confuses static checkers to dereference a pointer before
checking it.
