Bug id:6783 - Circulation restrictions dont work when other withdrawn reasons are used

Circulation restrictions work only when withdrawn reason (value 1) is selected.
If ones sets up other withdrawn reasons using authorized values, and selects
one of them (e.g. value 2), circulation restrictions don't work. This changes
fixes this problem.
