blk-mq-debugfs: clean up flag definitions
Make sure the spelled out flag names match the definition. This also adds a missing hctx state, BLK_MQ_S_START_ON_RUN, and a missing cmd_flag, __REQ_NOUNMAP. Signed-off-by: Omar Sandoval <osandov@fb.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Signed-off-by: Jens Axboe <axboe@fb.com>
