Johannes Berg d9f0109091 net: bonding: correctly annotate RCU in bond_should_notify_peers() 
[ Upstream commit 3ba359c0cd ]

RCU use in bond_should_notify_peers() looks wrong, since it does
rcu_dereference(), leaves the critical section, and uses the
pointer after that.

Luckily, it's called either inside a nested RCU critical section
or with the RTNL held.

Annotate it with rcu_dereference_rtnl() instead, and remove the
inner RCU critical section.
