net: Potential null skb->dev dereference
[ Upstream commit 0641e4fbf2f824faee00ea74c459a088d94905fd ]
When doing "ifenslave -d bond0 eth0", there is chance to get NULL
dereference in netif_receive_skb(), because dev->master suddenly becomes
NULL after we tested it.
We should use ACCESS_ONCE() to avoid this (or rcu_dereference())
