H A Dcpuid.cdiff 8b2fc445a7619fec55740d0a5785aae4bd1058f3 Mon Mar 02 17:56:12 CST 2020 Sean Christopherson <sean.j.christopherson@intel.com> KVM: x86: Refactor CPUID 0xD.N sub-leaf entry creation

Increment the number of CPUID entries immediately after do_host_cpuid()
in preparation for moving the logic into do_host_cpuid(). Handle the
rare/impossible case of encountering a bogus sub-leaf by decrementing
the number entries on failure.
