[PATCH] suspend: cleanup calling of power off methods.

In the lead up to 2.6.13 I fixed a large number of reboot problems by
making the calling conventions consistent.  Despite checking and double
checking my work it appears I missed an obvious one.

The S4 suspend code for PM_DISK_PLATFORM was also calling device_shutdown
without setting system_state, and was not calling the appropriate
reboot_notifier.

This patch fixes the bug by replacing the call of device_suspend with
kernel_poweroff_prepare.

Various forms of this failure have been fixed and tracked for a while.

Thanks for tracking this down go to: Alexey Starikovskiy, Meelis Roos

Ossman <drzeus-list@drzeus.cx>
