    nvc0/ir: start offset at texBindBase for txq, like regular texturing

    Curiously this has no actual effect. I think it's because the first 8
    textures are bound in multiple slots for some reason. However seems
    prudent to use these the same way as regular texturing, esp in the case
    where there are more than 8 textures bound.
