freedreno/ir3: fix fallout of unused false-depth elimination
Since we were MARK flag for both preventing loops, and tracking whether
instructions were used, we could end up in an infinite loop due to
bd2ca2bcdd. Instead invert the logic.. mark all instructions UNUSED
up front and clear the flag as we visit them.
