mm: fix return value of scan_lru_pages in memory unplug
commit f8f72ad5396987e05a42cf7eff826fb2a15ff148 upstream.
scan_lru_pages returns pfn. So, it's type should be "unsigned long"
not "int".
Note: I guess this has been work until now because memory hotplug tester's
machine has not very big memory....
