applesmc_create_key_backlight() allocates applesmc_led_wq before calling
led_classdev_register(). When register fails, the error is returned to
applesmc_init(), which jumps to out_light_sysfs and skips
applesmc_release_key_backlight(), leaking the workqueue.
Destroy the workqueue on the register failure path. The bug was introduced
when the inline init block was refactored into a helper that returns errors
directly, dropping the old out_light_wq unwind label.
