Previously we were erroneously passing the device softc to
acpi_stype_to_sstate in acpi_wake/run_sleep_prep instead of the ACPI
bus device softc.
Now, we pass the ACPI bus device softc when walking devices to prep for
sleep/wake.
Use the opportunity to pass the stype instead of the ACPI S-state to
acpi_wake_prep_walk.
