ALSA: sb: Fix PCM format bit calculation
The PCM format type in snd_pcm_format_t can't be treated as integer implicitly since it's with __bitwise. We have already a helper function to get the bit index of the given type, and use it in each place instead. This fixes sparse warnings like: sound/isa/sb/sb16_main.c:61:44: warning: restricted snd_pcm_format_t degrades to integer Signed-off-by: Takashi Iwai <tiwai@suse.de>
