ALSA: pcm: 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/core/pcm_native.c:2302:26: warning: restricted snd_pcm_format_t degrades to integer
sound/core/pcm_native.c:2306:54: warning: incorrect type in argument 1 (different base types)
sound/core/pcm_native.c:2306:54: expected restricted snd_pcm_format_t [usertype] format
sound/core/pcm_native.c:2306:54: got unsigned int [assigned] k
....
No functional changes, just sparse warning fixes.
