block: fix async_depth sysfs interface for mq-deadline
A previous commit added this feature, but it inadvertently used the wrong variable to show/store the setting from/to, victimized by copy/paste. Fix it up so that the async_depth sysfs interface reads and writes from the right setting. Fixes: 07757588e507 ("block/mq-deadline: Reserve 25% of scheduler tags for synchronous requests") Link: https://bugzilla.kernel.org/show_bug.cgi?id=215485 Reviewed-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
