Subject: [PATCH] Bug 28545: Noisy uninitialized warn at opac-MARCdetail.pl
 line 313

Test plan:
You do not even need a NULL value in a authorised value controlled
item field, a zero in damaged or withdrawn is enough to trigger the
warnings. (Because only the 1 is linked to an authvalue.)

Check your plack-opac-error.log before and after applying this change.

Without the patch I had at least four warnings per item: withdrawn,
lost, damaged and notforloan.
