Bug 40559: Fix noisy warning in MARCdetail 

Rebased for 25.06.
Resolves:
    Use of uninitialized value in string eq at /usr/share/koha/catalogue/MARCdetail.pl line 203.

Test plan:
Make sure that there is a combination of framework/field/subfield having
an entry in marc_subfield_structure where kohafield is NULL.
To force this for default fw on 020$q:
    update marc_subfield_structure
    set kohafield=NULL
    where tagfield='020' and tagsubfield='q' and frameworkcode='';
Pick a biblio in this framework having that field/subfield. Or create
a 020 with $q filled. Hit catalogue/MARCdetail now.
Without this patch, it triggers the warn. With this patch, it does not.
