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)
