Tweak initial generic-midi sync/smoothing

Browse Source 
"last_controllable_value" is using midi value range (0..127).
It is used to compare received midi-value with the actual controllable
for non-motorized surfaces, and this change allows the first
event to already be in_sync.

Previously the first MIDI-event was usually ignored (because
last_controllable_value was out of bounds or didn't match the 0..127
range.
