    argo: lower level of noisy connection-refused log
    
    Switch the log line to argo_dprintk() so it is enabled only in debug
    environments, as it can spam the logs when a dom0 service using the Argo
    hypercall tries to communicate with a domain that is still starting up.
    
    Note that this also lowers the log level to debug when the argo_dprintk()
    facility is enabled.
