    drm/i915/selftests: Wake the device before executing requests on the GPU

    To execute a requests requires us to have first woken the device, using
    the rpm wakeref (as the request needs to write to hardware to setup the
    context/ppGTT and execute on the GPU). So call intel_runtime_pm_get()
    around queuing the request; the request itself will then carry a wakeref
    until completion.
