nir/lower_int64: Fix [iu]mul_high handling

e551040c, which added a new mechanism for 64-bit imul which is more
efficient on BDW and later Intel hardware also introduced a bug where we
weren't properly walking both X and Y.  No idea how testing didn't find
this.

Fixes: e551040c ("nir/glsl: Add another way of doing lower_imul64 for gen8+"
Closes: mesa/mesa#6306
