[PATCH v5 04/10] crypto: ccp: Fix uapi definitions of PSP errors

[Dionna Glaze]

Additions to the error enum after the explicit 0x27 setting for
SEV_RET_INVALID_KEY leads to incorrect value assignments.

Use explicit values to match the manufacturer specifications more
clearly.

Fixes: 3a45dc2b419e ("crypto: ccp: Define the SEV-SNP commands")
