Bug 35460: Fix add and edit of hold rules in circulation rules table

Adding or editing following columns in circulation
rules table didn't work:
- Holds allowed (total)
- Holds allowed (daily)
- Holds per record (count)

At some point those columns were dropped from list of
saved columns in smart-rules.pl.

To test:
1. Create new rule or edit existing one.
2. Add or change values in following columns:
- Holds allowed (total)
- Holds allowed (daily)
- Holds per record (count
3. Save rule.
=> Note that columns have value "Unlimited" on them.
If you check database, columns haven't been saved.
4. Apply this patch.
5. Repeat steps 1. to 3.
=> Columns should now have values in them and they
are saved to database.
