memory_hotplug: ensure every online node has NORMAL memory
Old memory hotplug code and new online/movable may cause a online node
don't have any normal memory, but memory-management acts bad when we have
nodes which is online but don't have any normal memory. Example: it may
cause a bound task fail on all kernel allocation and cause the task can't
create task or create other kernel object.
So we disable non-normal-memory-node here, we will enable it when we
prepared.
