[PATCH] swsusp: kill crash when too much memory is free

From: Pavel Machek <pavel@ucw.cz>

If too much memory is free, swsusp dies in quite a ugly way.  Even when it
is not neccessary to relocate pagedir, it is proably still neccessary to
relocate individual pages.  Thanks to Kurt Garloff and Stefan Seyfried.
