delayed_controls: Remove reduandant firstSequence_
The DelayedControls implementation tracked the sequence numbers to
determine the offset if a device did not commence with a sequence number
of 0.
This guarantee is now handled by the V4L2VideoDevice.
Remove the firstSequence_ offset and the corresponding running_ flag
which was used to track setting firstSequence_ from the DelayedControls.
