mm: switch node meminfo Active & Inactive pages to Kbytes

commit 2d5c1be8870383622809c25935fff00d2630c7a5 upstream

There is a bug in the output of /sys/devices/system/node/node[n]/meminfo
where the Active and Inactive values are in pages instead of Kbytes.

Looks like this occurred back in 2.6.20 when the code was changed
over to use node_page_state().
