This is only used by IMA to retrieve an intermediate digest, so something will need to be fixed to support use of ML-DSA in IMA, but I don't know what yet. It doesn't, however, preclude the use of the rest of the code for module or kexec signature verification, so I think it's reasonable enough just to emit a warning and return an error here for now.
