ALSA: fireface: rename callback functions

Browse Source 
It's cleared that Fireface 400 transmits quadlet message for two purposes
at least; received MIDI messages and notification of knob control
operation. Nevertheless current implementation uses callback function name
just for MIDI messages.

This commit renames the callback functions.
