usb: Early failure when the first descriptor read fails or is invalid This may happen when using an USB1 device on a controller that only supports USB2 (e.g. EHCI). Reading the first descriptor will fail (read 0 byte), so we can abort the process at this point instead of failing later and wasting time. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>
