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.
