Exploit the cio siosl function to trigger logging in the FCP channel on qdio error conditions. Add a helper function in zfcp_qdio to ensure that tracing is only triggered once before calling qdio_shutdown. Trigger in zfcp for hardware logs are: - timeout for FSF requests to the FCP channel - "no recommendation" status from FCP channel - invalid FSF protocol status - stalled outbound queue - unknown request id on inbound queue - QDIO_ERROR_SLSB_STATE All of the above triggers run from the Linux qdio softirq context, so no additional synchronization is necessary for the handling of the ZFCP_STATUS_ADAPTER_SIOSL_ISSUED flag.
