KVM: x86: Hide IA32_PLATFORM_DCA_CAP[31:0] from the guest
The only thing reported by CPUID.9 is the value of
IA32_PLATFORM_DCA_CAP[31:0] in EAX. This MSR doesn't even exist in the
guest, since CPUID.1:ECX.DCA[bit 18] is clear in the guest.
Clear CPUID.9 in KVM_GET_SUPPORTED_CPUID.
Fixes: 24c82e576b78 ("KVM: Sanitize cpuid")
