[Intel-gfx] [PATCH v2 5/9] drm/i915: Add missing invalidate to g4x wm readout

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Let's not forget to mark the unused watermark levels as invalid
after the readout. The vlv/chv codepath has this but the g4x
didn't for some reason.
