[libvirt PATCH 02/25] qemu: remove dead code that setup cgroups for helper processes

[Pavel Hrdina <phrdina@xxxxxxxxxx>]

In both cases priv->cgroup will always be NULL because it is called
before the QEMU process is started and cgroups are configured.

In qemuProcessLaunch() the call order is following:

    qemuExtDevicesStart()
    ...
    virCommandRun()
    ...
    qemuSetupCgroup()

where qemuDBusStart() is called from qemuExtDevicesStart() but we
cgroups are created in qemuSetupCgroup().
