since the addition of srte_color to the comparison for bgp nexthops
it is possible to have several nexthops per prefix but since zebra
only stores a per prefix registration we should not unregister for
nh notifications for a prefix until all the nexthops for that prefix
have been deleted. Otherwise we can get into a deadlock situation
where BGP thinks we have registered but we have unregistered from zebra.
