[PATCH 03/18] leds: flash: leds-qcom-flash: switch to device_for_each_child_node_scoped()

Switch to device_for_each_child_node_scoped() to simplify the code by
removing the need for calls to fwnode_handle_put() in the error paths.
This also prevents possible memory leaks if new error paths are added
without the required call to fwnode_handle_put().
