drm/i915: Re-enable FBC WM if the watermark is good on gen6+

Browse source

If the calculated FBC watermark is no good, we simply disable FBC
watermarks. But we fail to re-enable them later if the calculated
watermark becomes good again. Fix that, but remember to leave FBC
watermarks disabled on ILK since that's required by some workarounds.
