This change extends the nd6 lock to protect the ND prefix list as well as the list of advertising routers associated with each prefix. To handle cases where the nd6 lock must be dropped while iterating over either the prefix or default router lists, a generation counter is used to track modifications to the lists. Additionally, a new mutex is used to serialize prefix on-link/off-link transitions. This mutex must be acquired before the nd6 lock and is held while updating the routing table in nd6_prefix_onlink() and nd6_prefix_offlink().
