Remove bad AOD->OCCLUDED transition

If a race condition occurs, such as launching navigation
in maps then immediately hitting the power button,
AOD->GONE was getting canceled incorrectly for OCCLUDED,
even though the device is asleep.

Fixes: 348583197
Flag: EXEMPT bugfix
Test: manual - this is a bad race condition when the
occluded signal comes in from WM. Steps to repro are
in the bug
