isl_pw_aff_scale: don't special case multiplication with zero
isl_pw_*_scale returns an empty result if a multiplication with zero
is being performed. We do this because zero is the default value
for polynomials. Affine expressions, by contrast, have no default value
and so we should not return an empty result in this case.
