xfrm: update x->lastused for every packet

x->lastused was only updated for outgoing mobile IPv6 packet.
With this fix update it for every, in and out, packet.

This is useful to check if the a SA is still in use, or when was
the last time an SA was used. lastused time of in SA can used
to check IPsec path is functional.
