leds: leds-ss4200: fix led_classdev_unregister twice in error handling

In current implementation, if device_create_file failed in register_nasgpio_led,
led_classdev_unregister will be executed twice.
( in register_nasgpio_led it calls led_classdev_unregister before return and in nas_gpio_init out_err )

This patch fixes it by only unregistering those that were successfully registered in out_err.
( not including last failed register_nasgpio_led call )
