As I understand it the last ACARS message - 00:29Z 2700 F/CTL SEC 3 FAULT - indicates a fault in the No 3 Spoiler and Elevator Controller. That being the case, the spoilers would have retracted. If the crew were following the Smoke Procedure they almost certainly would have been descending to FL100 when SEC 3 faulted.
I'm not a driver but I imagine that the retraction of the speed brake while executing an emergency descent would be troublesome.
