KVM: cpuid: remove has_leaf_count from struct kvm_cpuid_param
The has_leaf_count member was originally added for KVM's paravirtualization CPUID leaves. However, since then the leaf count _has_ been added to those leaves as well, so we can drop that special case. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
