ALSA: dummy: Use standard macros for fixing PCM format cast
Simplify the code with the new macros for PCM format type iterations.
This fixes the sparse warnings nicely:
sound/drivers/dummy.c:906:25: warning: restricted snd_pcm_format_t degrades to integer
sound/drivers/dummy.c:908:25: warning: incorrect type in argument 1 (different base types)
sound/drivers/dummy.c:908:25: expected restricted snd_pcm_format_t [usertype] format
sound/drivers/dummy.c:908:25: got int [assigned] i
No functional changes, just sparse warning fixes.
