ctrl_complete functions acquires ctx->lock and tries to unlink all queued urbs in case of errors through usb_unlink_urb func. In its turn usb_unlink_urb calls, through the hcd driver, usb_hcd_giveback_urb which calls ctrl_complete again. At this time, ctx->lock is already taken by the same function.
