slub: use N_NORMAL_MEMORY in can_free_to_pcs to handle remote frees

Browse source

Memory hotplug now keeps N_NORMAL_MEMORY up to date correctly, so make
can_free_to_pcs() use it.

As a result, when freeing objects on memoryless nodes, or on nodes that
have memory but only in ZONE_MOVABLE, the objects can be freed to the
sheaf instead of going through the slow path.
