    [SCSI] scsi_debug: disable clustering
    
    scsi_debug does at several places:
    
    for_each_sg(sdb->table.sgl, sg, sdb->table.nents, k) {
        kaddr = (unsigned char *)
                kmap_atomic(sg_page(sg), KM_USER0);
    
    We cannot do something like that with the clustering enabled (or we
    can use scsi_kmap_atomic_sg).
