Subject: [PATCH] dpaa2-eth: destroy workqueue at the end of remove function

The commit c55211892f46 ("dpaa2-eth: support PTP Sync packet one-step
timestamping") forgets to destroy workqueue at the end of remove
function.

Fix this by adding destroy_workqueue before fsl_mc_portal_free and
free_netdev.
