intel: Fix performance regression in Lightsmark since HiZ changes.
Since the refactor in d7b33309fe160212f2eb73f471f3aedcb5d0b5c1, depth in the miptree changed from 1 to 6, so we always decided it didn't match, and we would relayout to something that would still not "match". Improves performance 23.8% (+/- 1.1%, n=4) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=43329
