vc4: Fix inverted priority of instructions for QPU scheduling.

We were scheduling TLB operations as early as possible, and texture setup
as late as possible.  When I introduced prioritization, I visually
inspected that an independent operation got moved above texture results
collection, which tricked me into thinking it was working (but it was just
because texture setup was being pushed late).

total instructions in shared programs: 57651 -> 57486 (-0.29%)
instructions in affected programs:     18532 -> 18367 (-0.89%)
