[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. Signed-off-by: David L Stevens <dlstevens@us.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
