Subject: [PATCH] Bug 18296: C4::Items - Remove GetItemInfosOf

At this point this subroutine is only used once, from reserve/request.pl.
Since we already have the items, it's easy to populate the different
hashes as the rest of the code is expecting it.

Test plan:
You need to create analytical record relationships (
EasyAnalyticalRecords needs to be set). Link an item to a biblio using
the 'Edit > Link to host item' menu from the biblio detail page.
From the staff interface place a hold on the biblio. You should see the
items from the biblio and the one you just linked
