nvme: fix write zeroes pi
Write Zeroes sets PRACT when block integrity is enabled (as it should), but neglects to also set the reftag which is expected by reads. This causes protection errors on reads. Fix this by setting the reftag for type 1 and 2 (for type 3, reads will not check the reftag). Signed-off-by: Klaus Jensen <k.jensen@samsung.com> Reviewed-by: Martin K.
