usb: gadget: at91udc: don't overwrite driver data
The driver was converted to the new start/stop interface in f3d8bf34c2 ("usb: gadget: at91_udc: convert to new style start/stop interface"). I overlooked that the driver is overwritting the private data which is used by the composite framework. The udc driver doesn't read it, it is only written here.
