KVM: x86: Do host CPUID at load time to mask KVM cpu caps
Mask kvm_cpu_caps based on host CPUID in preparation for overriding the
CPUID results during KVM_GET_SUPPORTED_CPUID instead of doing the
masking at runtime.
Note, masking may or may not be necessary, e.g. the kernel rarely, if
ever, sets real CPUID bits that are not supported by hardware. But, the
code is cheap and only runs once at load, so an abundance of caution is
warranted.
No functional change intended.
