ospfd: Remove dup MaxAge LSA flood
Stop additional, unnecessary flooding of MaxAge LSAs.
When a MaxAge LSA is installed, if the LSA is prematurely aged or the LSA is
not self-originated, the LSA is flushed. This results in a the LSA being
flooded a second time and in some cases flooded back to the receiver
(unless the receiver is also the advertising router). A MaxAge'd LSA has
already been flooded in ospf_flood() as part of the LSA receive processing
(ospf_ls_upd). A self-originated LSA will be flooded from the originate/refresh
routine. Thus, in the install routine, a MaxAge'd LSA only needs to be added
to the MaxAge LSA list.
