To enable nested apicv support, we need per-cpu vmx
control MSRs:
1. If in-kernel irqchip is enabled, we can enable nested
posted interrupt, we should set posted intr bit in
the nested_vmx_pinbased_ctls_high.
2. If in-kernel irqchip is disabled, we can not enable
nested posted interrupt, the posted intr bit
in the nested_vmx_pinbased_ctls_high will be cleared.
Since there would be different settings about in-kernel
irqchip between VMs, different nested control MSRs
are needed.
