ospf6d: fix linkdown handling

Browse Source 
Ensure OSPFv3 handles link down even correctly.

OSPFv3 checks only the administrative status of a link instead of its
operative status. This prevents it up from detecting a real link down
event and reacting appropriately. Only protocol timer timeouts make it
detect a link down eventually. This patch makes it look for the operative
status of a link instead of admin status.
