Bug 10741: restore holdability of in-transit items on OPAC search results

In search results, one could not place a hold on an item in transit
and for loan (items.notforloan=0).  This appears when AllowOnShelfHolds
is allowed.

This patch repairs a regression introduced by the patch for bug 8975.

Test plan :
- Set AllowOnShelfHolds to on
- Create a record with a normal item : not lost, not withdrawn, not
  damaged, notforloan=0
- Index this record
- Perform a search on OPAC that returns this record (and others)
=> You see in actions "Place hold"
- Add this item in transit : /cgi-bin/koha/circ/branchtransfers.pl
- Re-perform the search on OPAC
=> You see in actions "Place hold" and item "in transit"
