Bug 21036: Fix uninitialized value within @itemnumber in string ne

Line from 16.11 log:
Use of uninitialized value within @itemnumber in string ne at /usr/share/koha/prodclone/reserve/modrequest.pl line 70.

Test plan:
Read the change. Not 100% identical (numeric zero) but should be enough.
This line is probably not needed at all.
