etnaviv: nir: do not call nir_lower_idiv(..) unconditionally

GPUs without native integers lower idiv in lower_int_to_float and
there is no need to call nir_lower_idiv(..) for such GPUs.

Fixes nir crashes I am seeing with gc2000_gles2 CI job.

Fixes: f532202f2d5 ("etnaviv: use nir_lower_idiv(..) before opt loop")
