Remove disconnected APs from BSS table if likely out-of-range
In some cases, after a sudden AP disappearing and reconnection to another AP in the same ESS, if another scan occurs, wpa_supplicant might try to roam to the old AP (if it was better ranked than the new one) because it is still saved in BSS list and the blacklist entry was cleared in previous reconnect. This attempt is going to fail if the AP is not present anymore and it'll cause long disconnections. Remove an AP that is probably out of range from the BSS list to avoid such disconnections. In particular mac80211-based drivers use the WLAN_REASON_DISASSOC_DUE_TO_INACTIVITY reason code in locally generated disconnection events for cases where the AP does not reply anymore.
