[PATCH] swsusp: rework swsusp_suspend

Browse Source 
This patch makes only the functions in swsusp.c call functions in snapshot.c
and not both ways.  It also moves the check for available swap out of
swsusp_suspend() which is necessary for separating the swap-handling functions
in swsusp from the core code.
