It is called right before local->ops->remove_interface() which means the
workqueue is flushed when it isn't even guaranteed that all interfaces are gone.
net/mac80211/main.c:553
static int ieee80211_stop(struct net_device *dev)
{
<snip>
switch (sdata->vif.type) {
case IEEE80211_IF_TYPE_MESH_POINT:
case IEEE80211_IF_TYPE_STA:
case IEEE80211_IF_TYPE_IBSS:
<snip>
flush_workqueue(local->hw.workqueue);

}
