Bug 31535: Fix warning - uninitialized value in string ne (MARCdetail.pl) 
Spotted at line 183 (older Koha version).

Test plan:
You need a NULL in the tab column of marc_subfield_structure. Hit this
page and check the logs.
This might convince you easier:
  my $tabloop=0; my $x; print "Empty string - True\n" if ( $x // q{} ) ne $tabloop;
  print "Zero - True\n" if ( $x // '0' ) ne $tabloop;
You should only see: Empty string - True proving that defaulting to '0'
would be a game changer.

=head1 NAME
MARCdetail.pl : script to show a biblio in MARC format
=head1 SYNOPSIS
=cut
=head1 DESCRIPTION
This script needs a biblionumber as parameter
It shows the biblio in a (nice) MARC format depending on MARC
parameters tables.
The template is in <templates_dir>/catalogue/MARCdetail.tt.
this template must be divided into 11 "tabs".
The first 10 tabs present the biblio, the 11th one presents
the items attached to the biblio
