Move recent_rotated and recent_scanned prints next to file lru lists
just because the pageout code in vmscan.c keeps track of how many of
the mem/swap backed and file backed pages are referenced, and the
higher the rotated/scanned ratio, the more valuable that cache is.
Move five lru lists and associated debug informations together can
make things convenience. :-)
