swsusp: refrigerator cleanups

swsusp: refrigerator cleanups

[Pavel Machek]

Hi!

This patch is from Nigel's swsusp2, it kills ugly #include <suspend.h>
from all over the tree, and makes code slightly nicer. I only left
those parts that do not change any code, please apply.

From: Nigel Cunningham <ncunningham@linuxmail.org>
