xfrm: Add a XFRM_STATE_AF_UNSPEC flag to xfrm_usersa_info
Add a XFRM_STATE_AF_UNSPEC flag to handle the AF_UNSPEC behavior for
the selector family. Userspace applications can set this flag to leave
the selector family of the xfrm_state unspecified. This can be used
to to handle inter family tunnels if the selector is not set from
userspace.
