Bug 11133: fix markup errors in OPAC place hold form HTML

There are markup errors in the OPAC place hold form which prevent it
from validating successfully. These errors don't seem to cause any
visual problem but can potentially cause problems when debugging
template logic.

To test, apply the patch and validate the page using your preferred
validator (since it's a page which requires login you'll have to upload
or paste the source). The page should validate successfully. Test when
placing holds on:

- a single item
- multiple items
- items which you cannot place on hold

Tested according to test plan and validated souce code with
W3C Validator.
