Well the concern there is that we expose the workqueue to the driver,

Wait actually, that isn't a concern. The flush_workqueue() was new in
commit b22cfcfca, before that drivers couldn't rely on it. It seems very
unlikely that in the meantime drivers have come to rely on it and we
didn't document this, so ... with the proposed change to sta_free_wk we
should be fine.
We still need to cancel the other mac80211 work items though, right?
I didn't understand your proposal for the sta_free_wk changes,
but I can at least work on tracking down the mac80211 work items
if that helps...
