LAKITU: Revert "mm/cgroup/reclaim: fix dirty pages throttling on cgroup v1"

This reverts commit 81a70c21d9170de67a45843bdd627f4cce9c4215.

This revert addresses an issue that we believe has been observed by
multiple people. This change doesn't appear to have an associated CVE.
It's also isolated to cgroup v1, which mitigates some risk.

BUG=b/425740673
TEST=presubmit, see bug
RELEASE_NOTE=Fixed an issue where some workloads could cause a full
system hang when running close to their memory limit.
