    spice: do not show error on cancel/close of auth dialog
    
    Mainly an issue for kiosk mode due the fact that it'll not quit the
    application on cancel. That means that authentication dialog can't
    really be canceled and showing an input error such as "wrong password"
    is misleading (no password should be taken in consideration on Cancel).
