[PATCH] memory hotadd: pgdat->node_present_pages fix
When pages are onlined, not only zone->present_pages but also
pgdat->node_present_pages should be refreshed.
This parameter is used to show information at
/sys/device/system/node/nodeX/meminfo via si_meminfo_node().
So, it shows strange value for MemUsed which is calculated
(node_present_pages - all zones free pages).
