Bug 8758: Remove useless code in circ/returns.pl

Before applying the patch I removed the [% IF %] from
around the markup which is removed by this patch. A table
of title and patron information appeared which I don't
remember ever seeing before. This tells me it's really
unused.

After applying the patch I performed some check-ins on both
checked out items and items which were on hold. All operations
completed normally.
