ALSA: wss: Fix sparse warning wrt PCM format type

The PCM format type is with __bitwise, and it can't be converted from
integer implicitly.  Instead of an ugly cast, declare the function
argument of snd_wss_get_format() with the proper snd_pcm_format_t
type.

This fixes the sparse warnings like:
  sound/isa/wss/wss_lib.c:551:14: warning: restricted snd_pcm_format_t degrades to integer
