leds: pca963x: 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(). After switching to the scoped variant, there is no longer need for a jump to 'err', as an immediate return is possible.
