Subject: drivers/leds/leds-gpio.c: properly initialize return value

drivers/leds/leds-gpio.c: properly initialize return value

In the event that none of the configs are set (CONFIG_LEDS_GPIO_PLATFORM,
CONFIG_LEDS_GPIO_OF, CONFIG_LEDS_GPIO_PLATFORM), we will return a bogus
value when initializing the module.
