- Clear the bssid set flag and channel in supplicant disconnect handler as this
can cause the station to recursively connect to the wrong AP in case
roaming through BTM mechanisms fails.
- Fix issue with incorrect blocking time calculation when blocking scan
issued for a single channel.
Executing supplicant WIFI_EVENT_STA_CONNECTED and WIFI_EVENT_STA_DISCONNECTED handlers in event-handler context can lead to concurrency issues.
Moving the functionality into 'wpa_sta_connected_cb' and 'wpa_sta_disconnected_cb' callbacks and execute in ppTask context.
