pcm: rate: Fix uninitialized variable warning

Browse source 
The recent gcc warning indicates the uninitialized variable commit_err:
  pcm_rate.c:1104:6: warning: ‘commit_err’ may be used uninitialized in this function [-Wmaybe-uninitialized]
     if (commit_err < 0)
         ^

Add a proper initialization to commit_err.

Fixes: 29041c5220 ("fix infinite draining of the rate plugin in SND_PCM_NONBLOCK mode")
