usb: udc: core: add device_del() call to error pathway
commit c93e64e91248becd0edb8f01723dff9da890e2ab upstream.
This patch fixes a bug in the error pathway of
usb_add_gadget_udc_release() in udc-core.c. If the udc registration
fails, the gadget registration is not fully undone; there's a
put_device(&gadget->dev) call but no device_del().
