Workqueue regression

Hi,

So, commit "Implement system-wide nr_active enforcement for unbound workqueues"
broke *something* and now performing a suspend-wakeup cycle on a Qualcomm
SC8280XP-based (arm64) platform hangs when performing the resume tasks,
presumably somewhere near PCIe reinitialization (but that may be a red herring).

Reverting the commit (and the ones on top of it due to conflicts) fixes
the issue on next-20240130 and later (plus some out-of-tree patches that
are largely unrelated).

Not sure where to start looking.
