Bug 24683: Optimize loop in ItemsAnyAvailableAndNotRestricted

Add cut-off shortcut (return from inside the loop) when first
"Any Available And Not Restricted" item found, because one is
enough for "Any".

Testing: no change visible for code behavior/results,
it is just faster because won't loop over the whole set.
