This is an aesthetic change in the fact that elog(ERROR) would not
cause -1 to be returned, still I agree that it is cleaner to do things
the way your patch does.  And the origin of the issue is I think that
the code of equalsJsonbScalarValue() has been copy-pasted from
compareJsonbScalarValue().

As that's really cosmetic, I would just change that on HEAD, or
perhaps others feel differently?
