KVM: x86: Add BHI_NO
commit ed2e8d49b54d677f3123668a21a57822d679651f upstream.
Intel processors that aren't vulnerable to BHI will set
MSR_IA32_ARCH_CAPABILITIES[BHI_NO] = 1;. Guests may use this BHI_NO bit to
determine if they need to implement BHI mitigations or not. Allow this bit
to be passed to the guests.
