Bug 33933: Only show use restriction once on OPAC detail page

Bug 33933: Only show use restriction once on OPAC detail page

This patch removes a regression from bug 32611 that caused the
use restriction text to be shown twice for "Available" items.

Test plan:
0. Apply patch
1. Go to http://localhost:8081/cgi-bin/koha/cataloguing/additem.pl?biblionumber=29
2. Edit item and add "Restricted access" for "5 - Use restrictions"
3. Go to http://localhost:8080/cgi-bin/koha/opac-detail.pl?biblionumber=29
4. Note that "Status" says "Available (Restricted access)" and there is no
duplicate "Restricted access" at the top of that table cell
