mei: remove flash_work_queue
Cancel each work properly and remove flash_work_queue.
Quoting documentation:
In most situations flushing the entire workqueue is overkill; you merely
need to know that a particular work item isn't queued and isn't running.
In such cases you should use cancel_delayed_work_sync() or
cancel_work_sync() instead.
