Do not add blacklist entries based on normal disconnect request cases 

There are number of cases where wpa_supplicant requests the current
connection to be disconnected before starting a new operation. Such
cases do not really indicate that there was an error in connecting or a
disconnection initiated by the AP, so do not add a temporary blacklist
entry in such sequences.
