staging: dpaa2-ethsw: destroy workqueue after deregistering the notifiers

Browse source

We should destroy the switch workqueue only after deregistering the
switchdev notifiers. Without this fix, we could end up with switchdev
notifications on a draining workqueue and also with a lock up since the
netdevice reference count is increased (in port_switchdev_event) and not
decreased ever (since the workqueue did not run).
