    fix bogus assumption if ddx has set up surface reg for z buffer
    
    this is wrong since even if ddx has not set up a surface reg to cover the z
    buffer we should pretend it has on those rv100 chips since they presumably do
    not do z buffer tiling if not using hyperz, so we can use linear addressing
    just the same. Doesn't seem to fix #13080, but it's wrong anyway and the bug
    almost certainly broke newer non-tcl chips.
