Bug 22440 will rewrite the route and make it even more efficient by
prefetching the related data instead of performing several queries in
loops.
In the meantime, we can make this controller perform better with a
simple intervention: load backends once, and use the
$request->_backend() setter to pre-set it before using the objects.
To test:
1. Perform any usual ILL requests listing, try having several
=> FAIL: Notice it takes a weird amount of time to load
2. Apply this patch
3. Restart all
4. Repeat 1
=> SUCCESS: It feels fast enough!
5. Sign off :-D
