nir/lower_tex: skip lower_tex_packing for the texture samples query 

Similar to other skips for texture queries that don't actually sample
the texture and which results are not packed.

We can't use nir_tex_instr_is_query() here to skip the lowering for all
queries since that causes regressions in Piglit. Apparently, we do want
to lower some of the query results. In particularly, the LOD query.
