The mchp_sparx5_probe() won't destroy workqueue created by
create_singlethread_workqueue() in sparx5_start() when later
inits failed. Add destroy_workqueue in the cleanup_ports case,
also add it in mchp_sparx5_remove()

Would be better if you destroy inside sparx5_start() before returning failure.

Alternatively you could add the destroy inside sparx5_cleanup_ports()
that will cover all error exits?

That works functionally, I have considered this modification as well.
Since I'm not quite sure on the naming, destroying the mact_queue
belongs to sparx5_cleanup_ports, which they don't contain now.

This is a fix so it needs a Fixes tag.
