Subject: [PATCH] l2tp: correctly handle ancillary data in the ip6 recv path

l2tp_ip6 is incorrectly using the IPv4-specific ip_cmsg_recv to handle
ancillary data.  This means that socket options such as IPV6_RECVPKTINFO are
not honoured in userspace.

Convert l2tp_ip6 to use the IPv6-specific handler.
