[igt-dev] [PATCH i-g-t] intel-ci: Disable i915_suspend at shrink

[Chris Wilson]

This test produces and awful, awful lot of redundant output as it tries
to find just the right amount of memory pressure to cause an
out-of-memory event in the middle of suspend. That is always quite a
slow process, taking 90s on a normal machine and 500+s on skl-y.
Furthermore, even when we do achieve the perfect setup, the test
frequently locks up and fails to resume with no indication that it is a
bug in the driver, the shrinker and oomkiller (plus i915) do not make for
a pleasant time!

Enough of Martin's whinging, I see no way of easily making this test
quieter, quicker and more efficacious, relegate it to the masochist only
stable.
