Leon Romanovsky c82b48b63a xfrm: prevent configuration of interface index when offload is used ...

Both packet and crypto offloads perform decryption while packet is
arriving to the HW from the wire. It means that there is no possible
way to perform lookup on XFRM if_id as it can't be set to be "before' HW.

So instead of silently ignore this configuration, let's warn users about
misconfiguration.
