Bug 28352: Only check authorised values mapped to DB fields

The errors reported seem to be caused by authorised values mapped to MARC fields
but not mapped to a koha field.

We should additionally make sure to check the Default framework

Also, adding comment to indicate we only check records with items, because we do

TO test:
1 - In a framework that is not the default map a MARC field to an authorised value, but not a koha field
2 - In SQL, force the kohafield to NULL for the mapping you just make
    UPDATE marc_subfield_structure SET kohafield = NULL WHERE frameworkcode='BKS' and authorised_value='HINGS_AS'
3 - perl misc/maintenance/search_for_data_inconsistencies.pl
4 - get the following errors:
Use of uninitialized value $tmp_kohafield in pattern match (m//) at /kohadevbox/koha/misc/maintenance/search_for_data_inconsistencies.pl line 151.
Use of uninitialized value $tmp_kohafield in substitution (s///) at /kohadevbox/koha/misc/maintenance/search_for_data_inconsistencies.pl line 154.
Can't call method "get_column" on an undefined value at /kohadevbox/koha/misc/maintenance/search_for_data_inconsistencies.pl line 157.
5 - Apply patch
6 - Repeat
7 - No more errors
