The ep0 reqs can't be dequeued unless the controller is reinited. Remove the ep0 dequeue codes or the hw cached irq may fetch wrong reqs ptr from the ep0 req queue causing kernel panic. 2. The locking sequence is unnecessary before the sync_cb_flag check and is error-prone. Remove it. Add ep0 req list empty check to prevent potential racing of the setup_status.
