[PATCH ipsec-next 3/3] xfrm: interface: not xfrmi_ipv6/ipip_handler twice

[Xin Long]

As we did in the last 2 patches for vti(6), this patch is to define a
new xfrm_tunnel object 'xfrmi_ipip6_handler' to register for AF_INET6,
and a new xfrm6_tunnel object 'xfrmi_ip6ip_handler' to register for
AF_INET.
