    kvm: x86: fix setting IA32_FEATURE_CONTROL with nested VMX disabled

    This patch is to fix the bug https://bugs.launchpad.net/qemu-kvm/+bug/120762

    IA32_FEATURE_CONTROL is pointless if not expose VMX or SMX bits to
    cpuid.1.ecx of vcpu. Current qemu-kvm will error return when kvm_put_msrs
    or kvm_get_msrs.
