KVM: SVM: Convert feature updates from CPUID to KVM cpu caps
Use the recently introduced KVM CPU caps to propagate SVM-only (kernel)
settings to supported CPUID flags.
Note, there are a few subtleties:
- Setting a flag based on a *different* feature is effectively
emulation, and must be done at runtime via ->set_supported_cpuid().
- CPUID 0x8000000A.EDX is a feature leaf that was previously not
adjusted by kvm_cpu_cap_mask() because all features are hidden by
default.
Opportunistically add a technically unnecessary break and fix an
indentation issue in svm_set_supported_cpuid().
No functional change intended.
