net: sparx5: unregister blocking notifier on init failure

Browse Source 
sparx5_register_notifier_blocks() registers the switchdev blocking
notifier before allocating the ordered workqueue. If the workqueue
allocation fails, the error path unregisters the switchdev and netdevice
notifiers, but leaves the blocking notifier registered.

Add a separate error label for the workqueue allocation failure path and
unregister the switchdev blocking notifier there.
