ALSA: usb-audio: Use pcm_for_each_format() macro for PCM format iterations

The new macro can fix the sparse warnings gracefully:
sound/usb/proc.c:73:31: warning: restricted snd_pcm_format_t degrades to integer
sound/usb/proc.c:73:38: warning: restricted snd_pcm_format_t degrades to integer
sound/usb/proc.c:73:61: warning: restricted snd_pcm_format_t degrades to integer

No functional changes, just sparse warning fixes.
