memory hotplug: fix unnecessary calling of init_currenty_empty_zone()
zone->present_pages is updated in online_pages(). But, __add_zone() can be
called twice or more before calling online_pages(). So,
init_currenty_empty_zone() can be called unnecessary times. It is cause of
memory leak of zone's wait_table.
