Eugene Grosbein 49f384cb47 ng_nat: avoid panic if attached directly to ng_ether and got short packet 
From the beginning, ng_nat safely assumed cleansed traffic
because of limited ways it could be attached to NETGRAPH:
ng_ipfw or ng_ppp only.

Now as it may be attached with ng_ether too, the assumption proven wrong.
Add needed check to the ng_nat. Thanks for markj for debugging this.
