net: Fix memory leak - vlan_info struct
In driver reload test there is a memory leak. The structure vlan_info was not freed when the driver was removed. It was not released since the nr_vids var is one after last vlan was removed. The nr_vids is one, since vlan zero is added to the interface when the interface is being set, but the vlan zero is not deleted at unregister. Fix - delete vlan zero when we unregister the device.
