nir_lower_to_source_mods: Don't sneek in an abs modifier from parent

Browse source 
If the abs source modifiers is not supported for the current
instruction because it is an instruction with three sources we
may still see a parent mov that has the `abs` modifier. In this
case we must not propagate that abs modifier from that parent
instructions.
