[Mesa-dev] [PATCH v3] nv50/ir: do not call textureMask() for surface ops

[Samuel Pitoiset]

That texture mask thing doesn't seem to be needed for surface ops, so
just as nve4+, let do that only for texture ops.

This fixes a segfault with 'test_surface_st' from
gallium/tests/trivial/compute.c on Fermi because this test uses sustp.
