backlight: Fix dimmed display doesn't go to sleep

Browse source 
Firmware didn't start sleep countdown if
1. Display was already dimmed
2. Fade out timer was set

You can reproduce this by:
1. Set fade out timer. For example, 500ms
2. Wait till display will be dimmed and go to sleep
3. Switch hold ON or plug headphones
