[Koha-patches] [PATCH] BUGFIX: $item is reference to hashref, not reference to hash.

[Joe Atzberger]

In fact, the double reference is useless overkill for this and another arg.
This patch relieves the error seen in logs as:
label-print-pdf.pl: Not a HASH reference at /home/atz/koha/production/intranet/modules/C4/Labels.pm line 1007., referer: http://staff-atz.dev.kohalibrary.com/cgi-bin/koha/labels/label-manager.pl?type=labels
