wifi: mac80211: fix TXQ error path and cleanup
We currently call ieee80211_txq_teardown_flows() as part of ieee80211_remove_interfaces(), but that's not really right in case of HW registration failures, specifically rate control. Call it separately to fix that issue. Reported-by: Zhengchao Shao <shaozhengchao@huawei.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
