nir: Fix clamping of uints for image store lowering. 

I botched some copy-and-paste and clamped to signed int max instead of
uint max.  Fixes KHR-GL46.shader_image_load_store.multiple-uniforms on
skl.

Fixes: d3e046e76c ("nir: Pull some of intel's image load/store format
conversion to nir_format.h")
