netjack2: handle 0 in sync frames

Browse source 
JACK2 only sends -1 as the frames, meaning we should take the value from
the negotiated period as the frames to process.

We however send the actual number of frames and use the sync value to
decide how many frames to process. We need to be careful because a value
of 0 will cause a division by 0 so treat <= 0 frames the negotiated period
size as well.
