Fix a crash seen on busy area border routers. The problem was a NULL

dereference in rde_summary_update(). Even though we merge in the new LSA
it may be suppressed because the remove happened less than 5 seconds ago.
So the second lsa_find() is still unable to locate the LSA and in this case
we may not access v->cost. Additionally only remove not yet deleted LSA
in lsa_remove_invalid_sums(), removing already removed entries removes also
the suppressed LSAs.
Problem found and fix tested by Pierre-Yves Ritschard. OK norby@
