ospf6d: Route locking (memory) cleanup

Browse Source 
* ospf6_route.c: (ospf6_route_best_next) Allows unlock route, even
  when there's no next route.  This is consistent with how
  ospf6_route_next() behaves.

* ospf6_intra.c: (ospf6_intra_prefix_lsa_remove) Make sure the last
  route considered is always unlocked.  This is needed when the for
  loop terminates because ospf6_route_is_prefix() returns zero.
