[ospfd] CID #15, remove redundant NULL check in ism_change_state

2006-05-12 Paul Jakma <paul.jakma@sun.com>

	* ospf_ism.c: (ism_change_state) NULL check on oi->area is
	  useless, it's always valid. Only possibility where it
 	  couldn't be is if there is a race between abr_task and
	  cleaning up oi's, in which case a NULL check here isn't going
	  to do anything. Fixes CID #15.
