ospfd: fix performance problem with redistribute delete
Doing redistribute delete with full BGP table was taking 30 minutes, this drops it down to less than a second. * ospf_lsa.c: (ospf_lsa_maxage) When flushing lots of entries the performance is terrible because it looks up each LSA entry through ospf_lsa_maxage_exist before deleting causing O(N^2) performance. Use a new OSPF_LSA_MAXAGE flag instead of scan - and maintain it. (ospf_lsa_maxage_exist) removed (ospf_lsa_maxage_delete) maintain OSPF_LSA_MAXAGE flag
