Subject: [PATCH] Bug 27861: Warning in C4/XSLT.pm - use of uninitialized value
 in numeric eq (==)

In C4/XSLT.pm :
 elsif ( exists $itemtypes->{ $item->effective_itemtype }
            && $itemtypes->{ $item->effective_itemtype }->{notforloan} == 1 )

itemtype.notforloan is null by default, its generated a warning in logs.

Test plan :
1) Choose a record with itemtype.notforloan = NULL
2) Perform a search in the OPAC which will return results which
   include the record using XSLT
3) See patch removed warning
