[ospfd] rename graceful to deferred, fix a tiny compile warning.

2005-11-26 Paul Jakma <paul.jakma@sun.com>

	* (general) s/graceful/deferred/ in all files, the former term
	   is confusing wrt OSPF Graceful-Restart.
	* ospfd.c: (ospf_deferred_shutdown_check) dont return
	  a function which returns void. SOS complains about this.
	  (ospf_finish)
