Bug 28057: Use the biblioitem's biblionumber for checking availability

Bug 28057: Use the biblioitem's biblionumber for checking availability

The loop here gets items from the record, plus analytic items. Because of this
we need to check more than 1 record - we decide to do this via biblioitems.

We need to preserve that, but when checking ItemsAnyAvailableAndNotRestricted we
cannot assume that the biblionumber and biblioitemnumber are the same (they should be
but this may not be the best of all possible worlds)

I simply switch the call here

To test:
1 - Apply patch
2 - Test placing holds on single bibs and multiple bibs
3 - Confirm it works as expected
