blk-mq: fix sysfs inflight counter
[ Upstream commit bf0ddaba65ddbb2715af97041da8e7a45b2d8628 ]
When the blk-mq inflight implementation was added, /proc/diskstats was
converted to use it, but /sys/block/$dev/inflight was not. Fix it by
adding another helper to count in-flight requests by data direction.
Fixes: f299b7c7a9de ("blk-mq: provide internal in-flight variant")
