Chanctx emulation didn't info IEEE80211_CONF_CHANGE_CHANNEL to drivers
during ieee80211_restart_hw (ieee80211_emulate_add_chanctx). It caused
non-chanctx drivers to not stand on the correct channel after recovery.
RX then behaved abnormally. Finally, disconnection/reconnection occurred.
So, set IEEE80211_CONF_CHANGE_CHANNEL when in_reconfig.
