mac80211: mlme: save ssid info to ieee80211_bss_conf while assoc
The ssid info of ieee80211_bss_conf is filled in ieee80211_start_ap() for AP mode. For STATION mode, it is empty, save the info from struct ieee80211_mgd_assoc_data, the struct ieee80211_mgd_assoc_data will be freed after assoc, so the ssid info of ieee80211_mgd_assoc_data can not access after assoc, save ssid info to ieee80211_bss_conf, then ssid info can be still access after assoc.
