Bug 31535: Fix warning - uninitialized value $mode in string ne (addbiblio.pl)

Line number varies across versions. (Should be L887 now.)
Resolves:
    Use of uninitialized value $mode in string ne at /usr/share/koha/cataloguing/addbiblio.pl line 845.

No test plan here. This is trivial. Read the patch.
