nir/lower_tex: ignore texture_index if tex_instr has deref src

Browse source 
texture_index is meaningless when a tex_instr has deref src.
Use var->data.binding instead.

This fixes the incorrect lowering on radeonsi where the same
lowering steps was applied to all tex_instr based on the needs
of the first one (since texture_index is always 0).
