ucm: suppress the no device (no UCM card) errors on request

Browse source 
It seems that users are confused when the UCM configuration
is not ready for the particular hardware. Actually, we don't
allow a fine grained message classification in alsa-lib and
UCM API. Allow suppression of this specific type of messages
on the application request (typically alsactl).
