KVM: cpuid: mask more bits in leaf 0xd and subleaves - EAX=0Dh, ECX=1: output registers EBX/ECX/EDX are reserved. - EAX=0Dh, ECX>1: output register ECX bit 0 is clear for all the CPUID leaves we support, because variable "supported" comes from XCR0 and not XSS. Bits above 0 are reserved, so ECX is overall zero. Output register EDX is reserved.
