sound: Improve sndstat nvlist feederchain format

Browse Source 
- Use snd_afmt2str() to display format conversions in feeder_format,
  instead of the plain hex value.
- Simplify feeder_rate contents.
- Print "ch" (e.g 2.1ch) after matrix values in feeder_matrix.
- Use snd_afmt2str() instead of a plain hex for the the rest of the
  feeder classes.
