uml: fix request->sector update
It is theoretically possible for a request to finish and be freed between writing it to the I/O thread and updating the sector count. In this case, the update will dereference a freed pointer. To avoid this, I delay the update until processing the next sg segment, when the request pointer is known to be good.
