HID: nvidia-shield: Remove led_classdev_unregister in thunderstrike_create

Avoid calling thunderstrike_led_set_brightness from thunderstrike_create
when led_classdev_unregister is called. led_classdev_unregister was called
from thunderstrike_create in the error path. Calling
thunderstrike_led_set_brightness in this situation is unsafe.
