[PATCH] usb: dwc3: gadget: pass a condition to dev_WARN_ONCE()

[Felipe Balbi]

instead of using:

        if (condition) {
                dev_WARN_ONCE(dev, true, "foo");
                return -EINVAL;
        }

let's use:

        if (dev_WARN_ONCE(dev, condition, "foo"))
                return -EINVAL;
