Hi,

Maybe I should not send patches this late at night as I end up
messing things up and spamming sleeping people. Sorry for this
version 4.

The real fix is in patch 2. The rest is a helper that adds
the with_intel_gt_pm_if_awake() (from Chris) and one more check
on the status of the engine before accessing it for clearing the
TLB.
