[PATCH] acpi_shutdown: Only prepare for power off on power_off
When acpi_sleep_prepare was moved into a shutdown method we
started calling it for all shutdowns.
It appears this triggers some systems to power off on reboot.
Avoid this by only calling acpi_sleep_prepare if we are going to power
off the system.
