3.16.37-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Sven Eckelmann <sven@xxxxxxxxxxxxx>
commit 420cb1b764f9169c5d2601b4af90e4a1702345ee upstream.
The untagged vlan object is only destroyed when the interface is removed
via the legacy sysfs interface. But it also has to be destroyed when the
standard rtnl-link interface is used.
Fixes: 5d2c05b21337 ("batman-adv: add per VLAN interface attribute framework")
