Bring back GT workaround application on the engine reset path

That i915.reset=1 helps suggests your bisect result might be valid, since the
indicated commit did remove some workaround application from the engine reset
path (which i915.reset=1 disables).

Would you be able to test this patch on top of a known bad (for you) drm-tip
kernel? It is exploratory patch at this stage only, which puts back a class of
workaround application on the engine reset path. If so, this patch should be
tested with the default i915.reset=2 modparam.
