mvpp2 uses a delayed workqueue to gather traffic statistics. On module removal the workqueue can be destroyed before calling cancel_delayed_work_sync() on its works. Fix it by moving the destroy_workqueue() call after mvpp2_port_remove().
Please post a new version with the flush_workqueue() removed.
