Bug 22083: Typo in circulation_batch_checkouts.tt

There is a typo in circulation_batch_checkouts.tt that makes Koha skip
a warning if the user cannot borrow due to circulation rules.

This patch corrects this typo.

To test:

1. In Administration > Global system preferences, 'Allow'
   BatchCheckouts and enter patron categories in
   BatchCheckoutsValidCategories
2. Go to Administration > Circulation and fines rules
3. Enter a rule where a certain category of patrons (that is in
   BatchCheckoutsValidCategories) cannot take out a particular item type
4. Search the catalog for an item of that item type
5. Copy the barcode
6. Go into patrons and find a patron of that category
7. Click on the Batch checkout tab
8. Paste the barcode in the box and click Check out
9. It should say 'Too many checked out'
10. Apply the patch
11. Try the check out again, it should show both warnings ('Too many
    checked out' and 'This patron can't check out this item per library
    circulation policy')
