IB/ipoib: rtnl_unlock can not come after free_netdev
[ Upstream commit 89a3987ab7a923c047c6dec008e60ad6f41fac22 ]
The ipoib_vlan_add function calls rtnl_unlock after free_netdev,
rtnl_unlock not only releases the lock, but also calls netdev_run_todo.
The latter function browses the net_todo_list array and completes the
unregistration of all its net_device instances. If we call free_netdev
before rtnl_unlock, then netdev_run_todo call over the freed device causes
panic.
To fix, move rtnl_unlock call before free_netdev call.
