vlan: Correctly handle device notifications for layered VLAN devices

Commit 30688a9 ([VLAN]: Handle vlan devices net namespace changing)
changed the device notifier to special-case notifications for VLAN
devices, effectively disabling state propagation to underlying VLAN
devices. This is needed for layered VLANs though, so restore the
original behaviour.
