[Mesa-stable] [PATCH] st/mesa: fix up result_src.type when doing i2u/u2i conversions

[Ilia Mirkin]

Even though it's a no-op, it's important to keep track of the type so
that we can pick the properly-signed op later on.

This fixes dEQP-GLES3.functional.shaders.precision.uint.highp_div_fragment,
which ended up using IDIV instead of UDIV.
