Huajun Li 4e09dcf20f USB: Remove races in devio.c 
There exist races in devio.c, below is one case,
and there are similar races in destroy_async()
and proc_unlinkurb().  Remove these races.

 cancel_bulk_urbs()        async_completed()
-------------------                -----------------------
 spin_unlock(&ps->lock);

                           list_move_tail(&as->asynclist,
		                    &ps->async_completed);

                           wake_up(&ps->wait);

                           Lead to free_async() be triggered,
                           then urb and 'as' will be freed.

 usb_unlink_urb(as->urb);
 ===> refer to the freed 'as'
