This reverts commit 56a232d93cea0ba14da5e3157830330756a45b4c.

The original patch changes the position of pm_wakeup_clear() for the
suspend call path, but other call paths with references to
freeze_processes() were not updated. This means that other call paths,
such as hibernate(), will not have pm_wakeup_clear() called.
