IMHO that message should not be there at all. If application relies on
it, then it must fail completely, warning is not enough.
For other uses it is optional.

Anyway, we can revert it even now, I added version check into cryptsetup
to detect kernel DM version and do not use that call if it is old.
And the same change will be needed in RHEL or people will complain...
