free: use SReclaimable in cached

The previous commit added all of slab into the cache value. The thing was is cached in this context is something you can get back and reclaim if under memory pressure. The problem was slab parameter includes both reclaimable and unreclaimable values which doesn't make sense in this context. This commit make cached only use the reclaimable component.
