ospf6d: Fixing a couple of issues with ospf6_route_remove () routine.

When a route_node has multiple ospf6_routes under it (common subnet case),
then the current implementation has an issue in adjusting the route_node->info
on a ospf6_route_remove() call.

The main reason is that it ends up using exact match to determine if the next
ospf6_route belongs to the same route_node or not. Fixing that part to use
rnode (the existing back-pointer to the route_node) from the ospf6_route to
determine that.

Also fixing some of the walks to turn them safe so that the route deletion is
fine.
