drm/i915: Use the active wm config for merging on ILK-BDW 

ilk_program_watermarks() is supposed to merge the active watermarks from
all pipes. Thus we need to use the active config too instead of some
precomputed stuff.

Fixes: aa36313686 ("drm/i915: Calculate watermark configuration during atomic check (v2)")
