[1/6] bfq-iosched: relocate bfqg_*rwstat*() helpers

Commit Message

Tejun Heo Nov. 7, 2019, 7:17 p.m. UTC

Collect them right under #ifdef CONFIG_BFQ_CGROUP_DEBUG.  The next
patch will use them from !DEBUG path and this makes it easy to move
them out of the ifdef block.

This is pure code reorganization.
