RCA:
1. when the ospf6 area is being deleted, the neighbor related information
was not being cleaned up.
2. when aggr route gets deleted from rt_aggr_tbl the corrsponding summary
route attched to the aggr route was not being deleted.
Fix:
Added the ospf6_neighbor_delete in ospf6_area_delete to free the
neighbor related information and added ospf6_route_delete while
freeing external aggr route to free the summary route.
