It's not just masking leaf 7. It's enabling it - before we passed 0
every time.
So we need to give it the same treatment as other leaves. We expose a
bit only if we explicitly support it in kvm, and it is enabled in the
host. See kvm_supported_word[01456] features for examples.
btw, we could also expose fsgsbase and rep/movsb (but in a separate
patch, please).
