Reboot logic in kernel/reboot will avoid calling kernel_power_off when pm_power_off is null, and instead uses kernel_halt. Change hibernate's power_down to follow the behavior in the reboot call.
Calling the notifier twice (once for SYS_POWER_OFF and again for SYS_HALT) causes a panic during hibernation on Kirkwood Openblocks A6 board.
