bridge: fix bridge netlink RCU usage
When the STP timer fires, it can call br_ifinfo_notify(),
which in turn ends up in the new br_get_link_af_size().
This function is annotated to be using RTNL locking, which
clearly isn't the case here, and thus lockdep warns:
===============================
[ INFO: suspicious RCU usage. ]
3.19.0+ #569 Not tainted
-------------------------------
net/bridge/br_private.h:204 suspicious rcu_dereference_protected() usage!
Fix this by doing RCU locking here.
Fixes: b7853d73e39b ("bridge: add vlan info to bridge setlink and dellink notification messages")
