Apparently I totally fumbled the loop condition when I removed the ARRAY_SIZE() stuff from the dbuf slice config lookup. Comparing the loop index with the active_pipes bitmask is utter nonsense, what we want to do is check to see if the mask is zero or not. Note that the code actually ended up working correctly despite the fumble, up until commiteef1739544("drm/i915: Allow !join_mbus cases for adlp+ dbuf configuration") when things broke for real.
