[PATCH] drm/i915/selftests: Set always_coherent to false when reading from CPU

[Nirmoy Das <nirmoy.das@intel.com>]

The previous commit 'commit 8d4ba9fc1c6c ("drm/i915/selftests: Pick
correct caching mode.")' was not complete as for non LLC  sharing platforms
cpu read can happen from LLC which probably doesn't have the latest
changes made by GPU.
