usb: dwc3: gadget: don't prevent gadget from being probed if we fail
In case we fail our ->udc_start() callback, we should be ready to accept another modprobe following the failed one. We had forgotten to clear dwc->gadget_driver back to NULL and, because of that, we were preventing gadget driver modprobe from being retried.
