block: fix async_depth sysfs interface for mq-deadline
commit 46cdc45acb089c811d9a54fd50af33b96e5fae9d upstream.
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")
