Florian Westphal 2b1dc6285c xfrm: pass struct net to xfrm_decode_session wrappers
Preparation patch, extra arg is not used.
No functional changes intended.

This is needed to replace the xfrm session decode functions with
the flow dissector.

skb_flow_dissect() cannot be used as-is, because it attempts to deduce the
'struct net' to use for bpf program fetch from skb->sk or skb->dev, but
xfrm code path can see skbs that have neither sk or dev filled in.

So either flow dissector needs to try harder, e.g. by also trying
skb->dst->dev, or we have to pass the struct net explicitly.

Passing the struct net doesn't look too bad to me, most places
already have it available or can derive it from the output device.
