Bug 30742: Remove 'bad_bibs' and send a list of holdable bibs

Currently place request gets a list of bad_bibs that is created via javascript on the
template. It ignores this list

Ths patch instead doesn't add info for bad bibs, and provides a list of the bibs that
can be held

To test:
1 - Attempt multi hold with some items that can be held, and one that cannot due to notforloan
2 - Fill in pickup locations and place hold
3 - Note hold is place on bib with no avilable items and hsows twice in results
4 - Apply patch
5 - repeat with another patron
6 - Note no aidditonal hold on record with notforloan items
7 - Note with with not for loan items appears only once in results
