Subject: [PATCH 4.1 149/159] rocker: free netdevice during netdevice removal

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ido Schimmel <idosch@...lanox.com>

[ Upstream commit 1ebd47efa4e17391dfac8caa349c6a8d35f996d1 ]

When removing a port's netdevice in 'rocker_remove_ports', we should
also free the allocated 'net_device' structure. Do that by calling
'free_netdev' after unregistering it.
