[gdm] Only retry login if user list enabled

    Only retry login if user list enabled
    
    The "User list disabled" codepath already handles
    reselecting OTHER on failure; running retry_login()
    doesn't make sense in that case.
    
    We really only want to do a retry if:
    1) The login window is still siting in AUTHENTICATION mode
    from a previous failed attempt
    2) The login window has a user list.
