ENGR00229291 EPDC: MX6: Treat fully-collided VOID update as a collision

The EPDC set the UPD_VOID (i.e. cancelled) bit in two cases:
1. No pixels needed updating
2. All pixels collided (COL bit also set)
The driver was miss-handling case 2. This fix causes case 2
to be treated as a collision and the update to be resubmitted.
