tu/lrz: Fix multiple depth attachment case with secondaries

Browse source 
This is a counterpart to the previous commit. When we have multiple
depth attachments, in the secondary we currently don't disable LRZ and
so we may need a valid LRZ fast-clear base.

Fixes: 4b5f0d98 ("tu: Overhaul LRZ, implement on-GPU dir tracking and LRZ fast-clear")
