commit 80946eb1f78c7cab565742576a5d877acddb355c

    firewall-cmd: show output on '--quiet --direct --passthrough'
    
    '--direct --passthrough' is special, because we don't know beforehand
    whether it will 'do' or 'show' something, i.e. whether we will
    show only status ('do something' case) or
    show only output of command and no status ('show something' case).
