Patrick McHardy cf2c014ade net: vlan: fix memory leak in vlan_info_rcu_free() 
The following leak is reported by kmemleak:

[   86.812073] kmemleak: Found object by alias at 0xffff88006ecc76f0
[   86.816019] Pid: 739, comm: kworker/u:1 Not tainted 3.9.0-rc5+ #842
[   86.816019] Call Trace:

[   86.816019]  [<ffffffff810d0b0b>] rcu_do_batch+0x261/0x4e7

The reason is that in vlan_info_rcu_free() we don't take the VLAN protocol
into account when iterating over the vlan_devices_array.
