[RFC][PATCH 1/4] swsusp: Remove incorrect code from user.c

["Rafael J. Wysocki" <rjw@sisk.pl>]

From: Rafael J. Wysocki <rjw@sisk.pl>

Make the code hibernation code in kernel/power/user.c be functionally equivalent
to the corresponding code in kernel/power/disk.c , as it should be.

The calls to the platform functions removed by this patch are incorrect.  They
should be replaced with some other "platform" operations that will be
introduced in one of the subsequent patches.
