This does not mean that the information for lost; it means that this
information was never received..

There seems to be two issues here. The driver did not indicate that
association had been completed (SIOCGIWAP event). In addition, I would
guess that the driver did not report the current SSID (SIOCGIWESSID)
when wpa_supplicant tried to figure out which network configuration
block would be used here.
