[PATCH 3.14 226/238] ipvs: fix ipv6 hook registration for local replies

[Greg Kroah-Hartman]

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Julian Anastasov <ja@xxxxxx>

commit eb90b0c734ad793d5f5bf230a9e9a4dcc48df8aa upstream.

commit fc604767613b6d2036cdc35b660bc39451040a47
("ipvs: changes for local real server") from 2.6.37
introduced DNAT support to local real server but the
IPv6 LOCAL_OUT handler ip_vs_local_reply6() is
registered incorrectly as IPv4 hook causing any outgoing
IPv4 traffic to be dropped depending on the IP header values.

Chris tracked down the problem to CONFIG_IP_VS_IPV6=y
