[PATCH v2] drivers:net:ethernet:Add missing fwnode_handle_put()

[Wang Ming]

In device_for_each_child_node(), we should have fwnode_handle_put()
when break out of the iteration device_for_each_child_node()
as it will automatically increase and decrease the refcounter.

This version adds 'Fixes:tag' compared to previous versions.
