kvm/s390: drop unpaired smp_mb
smp_mb on vcpu destroy isn't paired with anything, violating pairing rules, and seems to be useless. Drop it. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Message-Id: <1452010811-25486-1-git-send-email-mst@redhat.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com>
