IP-TFS input can be deferred while its reordering queue waits for a missing
sequence number. The VTI receive callback stores a pointer to the tunnel in
skb->cb, and the device can be removed and freed before the callback runs.

Keep only scalar tunnel metadata in an skb extension. The VTI callbacks
look up the device by ifindex under RCU and check its link configuration
before using its private data. If the VTI no longer exists, drop the
deferred packet. Use the same metadata to preserve tunnel mark handling
and IPv6 tunnel detection, and clear it when a new XFRM receive path starts
and after the callback completes.
