I added this although with the current patch it should not be required.
The led_cdev->fwnode_owned is anyways re-initialized at the beginning
of the 'led_classdev_register_ext'. It won't eat many cycles to zero it
here though so perhaps it's safer to just do it.

I am not sure I can finish and test the patch v7 today. So it may be
next year when I am able to send it... Sorry for the delay!
