Fix display of xfrm

When using iproute2 to display information on policies installed in kernel
(ip x p s) output is incorrect: IPv6 addresses printed as IPv4 addresses.
In case I am dealing with inter protocol policies where the template's address
family differs from those of the policy itself.
The patch attached solves this problem.
