crypto: ccp - Fix uAPI definitions of PSP errors

Browse Source 
commit b949f55644 upstream.

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

Use explicit values to match the manufacturer specifications more
clearly.

Fixes: 3a45dc2b41 ("crypto: ccp: Define the SEV-SNP commands")
