When checking a cloned request there is no need to check the overall

Why is the number of sectors in the request bigger than the queue limit?
Because we're checking the wrong limit.
blk_queue_get_max_sectors() is checking limits.max_sectors(), but the
requests are already fully formed and can extend up to
limits.max_hw_sectors().
