The only queues that really can't support a scheduler are those that do not have a gendisk associated with them, and thus can't be used for non-passthrough commands. In addition to those null_blk can optionally set the flag, which is a bad odd. Replace the null_blk usage with BLK_MQ_F_NO_SCHED_BY_DEFAULT to keep the expected semantics and then remove BLK_MQ_F_NO_SCHED as the non-disk queues never call into elevator_init_mq or blk_register_queue which adds the sysfs attributes.
