ac/radeonsi: add support for tex instr without a derefence

These are produced by nir_lower_bitmap(), adding the missing derefence
would cause other issues that need to be hacked around such as
skipping sampler lowering and uniform location assignment, so this
change seems the correct way to go.

Fixes 194 piglit crashes on radeonsi using NIR.
