Johannes Berg d5fee261df wifi: cfg80211: clear wdev->cqm_config pointer on free ... When we free wdev->cqm_config when unregistering, we also need to clear out the pointer since the same wdev/netdev may get re-registered in another network namespace, then destroyed later, running this code again, which results in a double-free.
