Bug 20825: (bug 19943 follow-up) call notforloan on itemtype instead of biblioitem

Bug 20825: (bug 19943 follow-up) call notforloan on itemtype instead of biblioitem

On bug 19943:
 -        elsif ($biblioitem->{'notforloan'} == 1){
 +        elsif ($biblioitem->notforloan == 1){

The biblioitems table does not contain a notforloan column, this comes
from the item type.

This bug only appears when item type is defined at biblio level
(item-level_itypes=0)

Test plan:
Set item-level_itypes = biblio
Check an item out

Without this patch it explodes with
"The method notforloan is not covered by tests!"

I reproduced the error condition and verified the tests failed without
this patch. After this patch is applied, tests pass and checkout
succeeds.
