Michael Roth 801baa693c x86/sev: Move MSR-based VMGEXITs for CPUID to helper 
This code will also be used later for SEV-SNP-validated CPUID code in
some cases, so move it to a common helper.

While here, also add a check to terminate in cases where the CPUID
function/subfunction is indexed and the subfunction is non-zero, since
the GHCB MSR protocol does not support non-zero subfunctions.
