Daniel Sneddon 15d6de3746 KVM: x86: Add BHI_NO 
commit ed2e8d49b5 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.
