leds: gpio: Clear error pointers for skipped LEDs

gpio_led_get_gpiod() returns an error pointer when a platform-data
LED's GPIO is unavailable. gpio_led_probe() skips registration in that
case, but leaves the error pointer in led_dat->gpiod.

The skipped entry remains included in priv->num_leds. During shutdown,
gpio_led_shutdown() walks those entries and passes the error pointer to
gpio_led_set(), producing:

  gpiod_set_value: invalid GPIO (errorpointer: -ENOENT)

Clear led_dat->gpiod before skipping the LED so skipped entries do not
retain error-valued descriptors.
