Jim Mattson 86c4f0d547 KVM: x86: Mask off reserved bits in CPUID.8000001FH 
KVM_GET_SUPPORTED_CPUID should only enumerate features that KVM
actually supports. CPUID.8000001FH:EBX[31:16] are reserved bits and
should be masked off.

Fixes: 8765d75329a3 ("KVM: X86: Extend CPUID range to include new leaf")
