ospf6d: Handling Topo Change in GR-HELPER mode for max-age lsas

Description:
OSPF6 GR HELPER router should  consider as TOPOCHANGE when
it receives lsas with max age and should exit from Helper.
But, it is not exiting from helper because this max age lsa is
considered as duplicated lsa since the sender uses same seq
number for max age lsa from the previous lsa update.
Currently, topo change is not considered for duplicated lsas.
So removed the duplicated check when validating TOPOCHNAGE.
