ALSA: xen: Use standard pcm_format_to_bits() for ALSA format bits
The open codes with the bit shift in xen_snd_front_alsa.c give sparse warnings as the PCM format type is with __bitwise. There is already a standard macro to get the format bits, so let's use it instead. This fixes sparse warnings like: sound/xen/xen_snd_front_alsa.c:191:47: warning: restricted snd_pcm_format_t degrades to integer Signed-off-by: Takashi Iwai <tiwai@suse.de>
