gk104/ir: sampler doesn't matter for txf
We actually leave the sampler unset for OP_TXF, which caused the GK104+ logic to treat some texel fetches as indirect. While this works, it's incredibly wasteful. This only happened when the texture was > 0 (since sampler remained == 0). Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Cc: "11.0 11.1" <mesa-stable@lists.freedesktop.org>
