[PATCH v3 6/8] KVM: X86: Move kvm_x86_ops.update_vcpu_model() into kvm_update_vcpu_model()

[Xiaoyao Li <xiaoyao.li@intel.com>]

kvm_x86_ops.update_vcpu_model() is used to update vmx/svm vcpu settings
based on updated CPUID settings. So it's supposed to be called after
CPUIDs are fully updated, i.e., kvm_update_cpuid().

Currently, kvm_update_cpuid() only updates CPUID bits of OSXSAVE, APIC,
OSPKE, MWAIT, KVM_FEATURE_PV_UNHALT and ebx of (leaf 0xD, subleaf 0x0),
ebx of (leaf 0xD, subleaf 0x1). None of them is consumed by vmx/svm's
update_vcpu_model().

So there is no dependency between kvm_x86_ops.update_vcpu_model() and
kvm_update_cpuid(). Move kvm_x86_ops.update_vcpu_model() into
kvm_update_vcpu_model() make it more reasonable.
