leds: lp50xx: Fix an error handling path in 'lp50xx_probe_dt()'
In case of memory allocation failure, we must release some resources as done in all other error handling paths of the function. 'goto child_out' instead of a direct return so that 'fwnode_handle_put()' is called when we break out of a 'device_for_each_child_node' loop.
