ip xfrm state: Allow different selector family

My previous commit introduced a patch to allow for states with different
ip address families for selector and id. The must have somehow been a
mixup of the patch I tested and the one I send, so the patch sent breaks
the iproute2 build. This patch fixes this. My apologies.
