Sean Christopherson 0497d2ac9b KVM: VMX: Check KVM CPU caps, not just VMX MSR support, for XSAVE enabling
Check KVM CPU capabilities instead of raw VMX support for XSAVES when
determining whether or not XSAVER can/should be exposed to the guest.
Practically speaking, it's nonsensical/impossible for a CPU to support
"enable XSAVES" without XSAVES being supported natively.  The real
motivation for checking kvm_cpu_cap_has() is to allow using the governed
feature's standard check-and-set logic.
