net: microchip: sparx5: Fix missing destroy_workqueue of mact_queue

[ Upstream commit 7b8232bd ]

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()
