fix(wpa_supplicant): Clear bssid flag and channel in supplicant disconnect handler

Browse Source 
- 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.
