When passing a range of ready-to-process SBALs to the upper-layer driver, use the available 'count' instead of calculating the distance between the first_to_check and first_to_kick cursors. This simplifies the logic of the queue-scan path, and opens up the possibility of scanning all 128 SBALs in one go (as determining the reported count no longer requires wrap-around safe arithmetic on the queue's cursors).
