The call of of_get_child_by_name() will cause refcount incremented
for leds, if it succeeds, it should call of_node_put() to decrease
it, fix it.

Fixes: 01e5b728e9e4 ("net: phy: Add a binding for PHY LEDs")

v3:

v2:
- Split into 2 patches.
- Use of_node_put() rather than __free() to fix it.

This is a fix. You were asked to break it out of the series, and post
it to net, not net-next.

Jonathan, please could you step in and do some mentoring. Huawei is
big enough it should not need Maintainers to teach its developers the
basics.
