nir: fix missing increments of num_inputs/num_outputs

Note: not quite perfect, we should use type_size vfunc (in
compiler_options or nir_shader?) to determine how much we
increment num_inputs/outputs/uniforms.  But we don't have
that yet, so let's at least fix things for the existing
users of these passes.
