[PATCH] mm, memory_hotplug: pass next_memory_node to new_page_nodemask()

[Wei Yang <richard.weiyang@gmail.com>]

As the document says new_page_nodemask() will try to allocate from a
different node, but current behavior just do the opposite by passing
current nid as preferred_nid to new_page_nodemask().

This patch pass next_memory_node as preferred_nid to new_page_nodemask()
to fix it.
