Account when the next nd6_timer_to is scheduled in nd6_timer()
otherwise nd6_llinfo_settimer() might wrongly assume that a timeout is
already scheduled earlier and not schedule one itself. This in turn
lead to the neighbor cache no longer updating because neighbor
solicitations were not send.
Observed by many.
