nvc0: avoid tex read fault from compute shaders on GK110
After some investigation, it seems like that disabling the UNK02C4
command avoid a read fault with texelFetch() from a compute shader.
I have no clue on what this method actually does, but this avoid the
GPU to hang with basic-texelFetch.shader_test without introducing any
compute-related regressions.
