Subject: [PATCH] pcm: route: Don't handle no matching chmap as a serious error

When find_matching_chmap() returns an error for the non-matching
chmap, the caller, snd_pcm_route_open(), also returns an error
although it shouldn't be handled as the fatal error.  This results in
the probe error with PulseAudio and it gives no real output in the
end.
