KVM: x86: Refactor CPUID 0xD.N sub-leaf entry creation

Browse source

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.
