ipv6: Handle route deletion notification
For the purpose of route offload, when a single route is deleted, it is
only of interest if it is the first route in the node or if it is
sibling to such a route.
In the first case, distinguish between several possibilities:
1. Route is the last route in the node. Emit a delete notification
2. Route is followed by a non-multipath route. Emit a replace
notification for the non-multipath route.
3. Route is followed by a multipath route. Emit a replace notification
for the multipath route.
In the second case, only emit a delete notification to ensure the route
is no longer used as a valid nexthop.
