bgpd: Prevent the ebgp ipv6 sender from changing of nexthop in a special case.
Prevent the ebgp sender from changing the nexthop( which is same as the ebgp neighbour ipv6 address),
while sending updates to its ipv6 neighbor.So,if the nexthop of the ipv6 route is same as the ipv6
neighbour address do not change the next hop to your own ip.
