[PATCH v2] leds: lp50xx: add missing fwnode_handle_put in error handling case

[Qinglang Miao]

Fix to set ret and goto child_out for fwnode_handle_put(child)
in the error handling case rather than simply return, as done
elsewhere in this function.

Fixes: 242b81170fb8 ("leds: lp50xx: Add the LP50XX family of the RGB LED 
driver")
