[Intel-gfx] [PATCH] drm/i915: Really calculate the cursor ddb based on the highest enabled wm level

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

I added the loop but neglected to actually pass the level to the
function. So we were just looping 8 times calculating the exact
same thing every time.

Fixes: df331de3f8aa ("drm/i915: Allocate enough DDB for the cursor")
