flow_dissector: use RCU protection to fetch dev_net()
[ Upstream commit afec62cd0a4191cde6dd3a75382be4d51a38ce9b ]
__skb_flow_dissect() can be called from arbitrary contexts.
It must extend its RCU protection section to include
the call to dev_net(), which can become dev_net_rcu().
This makes sure the net structure can not disappear under us.
