Simon Glass fb8a5ffc77 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.
