Joel Fernandes (Google) 3826909635 rcu/kfree: Fix kfree_rcu_shrink_count() return value 
As per the comments in include/linux/shrinker.h, .count_objects callback
should return the number of freeable items, but if there are no objects
to free, SHRINK_EMPTY should be returned. The only time 0 is returned
should be when we are unable to determine the number of objects, or the
cache should be skipped for another reason.
