Bug 14821: Do not list not returned items

On the checkin page, the table is always filled with info of the scanned
barcode, even if the checkin has failed.
When the checkin fails, there is already an error displayed, so there is
no need to keep a row for fails.

Test plan:
Confirm that the failed checkins don't appear anymore in the checkin
table.
- checkin an item which is not issued;
- BlockReturnOfWithdrawnItems is set and item is withdrawn;
- Not returned at the right place;
- privacy=2 and AnonymousPatron not correctly set;

Before this patch this behavior existed only for bad barcode.
