list-objects-filter-options: always supply *errbuf 

Making errbuf an optional argument complicates error reporting. Fix this
by making all callers supply an errbuf, even if they may ignore it. This
will be important in follow-up patches where the filter-spec parsing has
more pitfalls and possible errors.
