Following the PI operation inside nvme/perf, add 2 PI options into fio engine option. SPDK ioengine will check whether PI information should be generated or verified. Running with PI setting, following settings are required: 1. In fio configure file, add PRACT like "pi_act=0", and set PRCHK by flags(GUARD|REFTAG|APPTAG), like "pi_chk=GUARD". 2. Format device namespace with proper PI setting 3. In fio configure file, blocksize should be set as the sum of data and metadata.
