Bug 8809 : BGP Manager / neighbor summary for VPNv6 wrongly parsed

Instead of filtering the BGP neighbor IP with IPv6 address, the
filtering is done against IPv4 neighbor addresses. There is no need to
match with IPv6 neighbors, since it is related to underlays tunnels, and
not overlays information like VPNv6.
