[PATCH] leds: fix ifdef check for gpio_led_register_device()

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

gpio_led_register_device() is built whenever CONFIG_LEDS_GPIO_REGISTER is
enabled, and this may be used even when CONFIG_NEW_LEDS is turned off.

However, the stub declaration in the header is provided for all configs
without CONFIG_NEW_LEDS, resulting in a build failure:

drivers/leds/leds-gpio-register.c:24:1: error: redefinition of 'gpio_led_register_device'
   24 | gpio_led_register_device(int id, const struct gpio_led_platform_data *pdata)
      | ^
include/linux/leds.h:646:39: note: previous definition is here

Change the #ifdef check to match the definition.
Note: this apparently took years of randconfig builds to hit, since
a number of other drivers just 'select NEW_LEDS' anyway.
