[Intel-gfx] [PATCH] drm/i915/selftests: Show the RC6 residency on parking failure

[Intel-gfx] [PATCH] drm/i915/selftests: Show the RC6 residency on parking failure

[Chris Wilson]

Include the current RC6 residency counter in the error message, so that
if we fail to park and manually enter RC6 we can see if the counter has
a particularly suspect value (such as 0).
