usb: dwc3: gadget: don't prevent gadget from being probed if we fail
commit cdcedd6981194e511cc206887db661d016069d68 upstream.
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.
