usb: gadget: at91udc: Don't check for ep->ep.desc
Earlier we used to check for ep->ep.desc to figure out if this ep has already been enabled and if so, abort. Ido Shayevitz removed the usb_endpoint_descriptor from private udc structure 5a6506f00 ("usb: gadget: Update at91_udc to use usb_endpoint_descriptor inside the struct usb_ep") but did not fix up the ep_enable condition because _now_ the member is always true and we can't check if this ep is enabled twice.
