KVM: s390: use created_vcpus in more places

[ Upstream commit 241e3ec0faf5ab1a0d9b1f6c43eefa919fb9c112 ]

commit a03825bbd0c3 ("KVM: s390: use kvm->created_vcpus") introduced
kvm->created_vcpus to avoid races with the existing kvm->online_vcpus
scheme. One place was "forgotten" and one new place was "added".
Let's fix those.
