mm, vmscan: cleanup lru size claculations
commit fd538803731e50367b7c59ce4ad3454426a3d671 upstream.
lruvec_lru_size returns the full size of the LRU list while we sometimes
need a value reduced only to eligible zones (e.g. for lowmem requests).
inactive_list_is_low is one such user. Later patches will add more of
them. Add a new parameter to lruvec_lru_size and allow it filter out
zones which are not eligible for the given context.
