Ravi Bangoria d922056215 KVM: SEV-ES: Disallow SEV-ES guests when X86_FEATURE_LBRV is absent 
As documented in APM[1], LBR Virtualization must be enabled for SEV-ES
guests. So, prevent SEV-ES guests when LBRV support is missing.

[1]: AMD64 Architecture Programmer's Manual Pub. 40332, Rev. 4.07 - June
     2023, Vol 2, 15.35.2 Enabling SEV-ES.
