[PATCH 2/3] kvm-s390: update vcpu->cpu - rebased

[ehrhardt@linux.vnet.ibm.com]

From: Christian Ehrhardt <ehrhardt@linux.vnet.ibm.com>

As requested this is a rebased patch on top of the already applied v3
of the patch series.

kvm on s390 formerly ignored vcpu->cpu.
This patch adds set/unset vcpu->cpu in kvm_arch_vcpu_load/put to allow
further architecture unification e.g. let generic code not find -1 on
currently scheduled vcpus.
