In split-brain prevention with tcp arbitration if the OpenSAF 2N is switched-over when the tcp arbitration server is down, the AMF crashes due to can not set active in consensus service.
In this case it should ignore setting failed because two SCs still see each others.

    amf: prevent AMF crashes during switch-over [#3386]
    
    When TCP arbitration server is down during switch-over,
    standby node fails to promote itself to active in the
    consensus service which leads to AMF crashing.
    
    This fix removes the assertion that triggers the crash,
    allowing the switch-over process to complete more gracefully.
