usb: wusbcore: avoid stack overflow in URB enqueue error path This patch modifies wa_urb_enqueue to return an error and not call the urb completion routine if it failed to enqueue the urb because the HWA device is gone. This prevents a stack overflow due to infinite submit/complete recursion when unplugging the HWA while connected to a HID device.
