[MSGINA] Simplify the auto logon code path
- Get rid of DoAutoLogon() and the AutoLogonState variable. - Handle the auto logon in the normal logon code path instead. - Set bAutoAdminLogon to FALSE on a successful login. This will prevent another automatic logon after a logoff. - The IgnoreShiftOverride feature got lost by this change but I will add it again.
