led: Return -ENODEV if the LED device cannot be found
We normally use -ENODEV for a missing device, rather than -ENOENT. The latter is reserved for when we have a device but cannot find something within it. Also avoid looking at the root LED device since it is only a container. Signed-off-by: Simon Glass <sjg@chromium.org>
