Steffen Klassert 19d7df69fd xfrm: Refuse to insert 32 bit userspace socket policies on 64 bit systems ...

We don't have a compat layer for xfrm, so userspace and kernel
structures have different sizes in this case. This results in
a broken configuration, so refuse to configure socket policies
when trying to insert from 32 bit userspace as we do it already
with policies inserted via netlink.
