    Always show stack status reason in topology

    Currently, only when the stack is in error status, the stack status
    reason will be displayed, otherwise, there will be two line with
    exactly same words, and this makes the enduser confuse. So fixes
    this by changing to not show anything when stack in not in error
    status.
