[SCSI] zfcp: Add support for unchained FSF requests
Add the support to send CT and ELS requests as unchained FSF requests. This is required for older hardware and was somehow omitted during the cleanup of the FSF layer. The req_count and resp_count attributes are unused, so remove them instead of adding a special case for setting them. Also add debug data and a warning, when the ct request hits a limit.
