LU-3754 mdt: Enable data_version control

When LU-1333 was landed, all HSM infrastructure was not yet landed and
it was not possible to archived a file. As a consequence, the original
patch did not compare on-disk archived data version and current file
data version.
Now, everything required is there and we should enable this
verification.
