Bug 20546: Display shelving location on checkin

Currently, the sehlving location is not being displayed in the table
of checked in items on <intranet>/cgi-bin/koha/circ/returns.pl

To test:
- Make sure you have a couple of books with a value for shelving location (952$c)
- Check the books out
- Check the books in
- Verify nothing is displayed in the "Shelving location" column
- Apply this patch
- Check the books out and in again
- Verify the shelving location is now being displayed
