ospfd: Discriminate better when selecting links between vertices in SPF
* ospf_spf.c: (ospf_get_next_link) One must check the vertex type, Router or
Network, to select type link to match against. Link type 1 has neighbour
router ID in link_id and link type 2 has IP address of DR. Since router
id may have same value as an existing IP address one risks matching a
router ID against a DR.
