usb: renesas_usbhs: gadget: fix unused-but-set-variable warning
The commit b8b9c974afee ("usb: renesas_usbhs: gadget: disable all eps when the driver stops") causes the unused-but-set-variable warning. But, if the usbhsg_ep_disable() will return non-zero value, udc/core.c doesn't clear the ep->enabled flag. So, this driver should not return non-zero value, if the pipe is zero because this means the pipe is already disabled. Otherwise, the ep->enabled flag is never cleared when the usbhsg_ep_disable() is called by the renesas_usbhs driver first.
