[neighbour] Use discovery protocol field to identify incomplete neighbours

Browse Source 
Use the discovery protocol pointer field (rather than the running
state of the discovery timer) to determine whether or not neighbour
discovery is ongoing, as a precursor to allowing the timer to be
(ab)used for adding deliberate latency to transmitted packets.
