The end-to-end integrity ublk selftest test_integrity_02 requires a relatively recent fio version to support I/O with integrity buffers. Add a version test_integrity_03 that uses the block layer's auto integrity path instead. The auto integrity code doesn't check the application tag, and doesn't indicate the bad guard/ref tag (just returns EILSEQ). But it's a good smoke-test of the ublk integrity code and provides coverage of the auto integrity path as well.
