page-allocator: reset wmark_min and inactive ratio of zone when hotplug happens
Solve two problems.
Whenever memory hotplug sucessfully happens, zone->present_pages
have to be changed.
1) Now memory hotplug calls setup_per_zone_wmark_min only when
online_pages called, not offline_pages.
It breaks balance.
2) If zone->present_pages is changed, we also have to change
zone->inactive_ratio. That's because inactive_ratio depends on
zone->present_pages.
