[Intel-gfx] [PATCH 3/6] drm/i915: Check SAGV wm min_ddb_alloc rather than plane_res_b

[Ville Syrjala]

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

For non-transition watermarks we are supposed to check min_ddb_alloc
rather than plane_res_b when determining if we have enough DDB space
for it. A bit too much copy pasta made me check the wrong thing.
