ACPI: Do not prepare for hibernation in acpi_shutdown

Browse source 
Since we are now explicitly calling hibernation_ops->prepare() before
hibernation_ops->enter() in hibernation_platform_enter() (defined in
kernel/power/disk.c), ACPI should not call acpi_sleep_prepare(ACPI_STATE_S4)
from acpi_shutdown().
