nir: Don't use ffma in nir_lower_wpos_ytransform(). ffma is an explicitly fused multiply add with higher precision. The optimizer will take care of promoting mul/add to fma when it's beneficial to do so. This fixes failures on Gen4-5 when using this pass, as those platforms don't actually implement fma().
