Revert "workqueue: Make wq_adjust_max_active() round-robin pwqs while activating"

This reverts commit ddb232dc0f1339f9ed506730fd6bee6f5e3dcb37 which is
commit c5404d4e6df6faba1007544b5f4e62c7c14416dd upstream.

The workqueue patches backported to 6.8.y caused some reported
regressions, so revert them for now.
