[IPV6]: Fix per-socket multicast filtering in sk_reuse case 



per-socket multicast filters were not being applied to all sockets
in the case of an exact-match bound address, due to an over-exuberant
"return" in the look-up code. Fix below. IPv4 does not have this problem.

Thanks to Hoerdt Mickael for reporting the bug.
