ucm: Fix uninitialized err in snd_use_case_set()

The compiler warns like:
  main.c:1664:9: warning: 'err' may be used uninitialized in this function [-Wmaybe-uninitialized]

and actually there are slight code paths that slip.
This patch adds the proper initializations to 0 to return the success
code in these code paths.
