suspend: cleanup reference to swsusp_pg_dir[]
swsusp_pg_dir[] is used for suspend, but not for hibernation. clean-up the ifdefs which worked by accident, while implying the opposite. Delete the __nosavedata, which also implied the opposite. Some day we may optimize CONFIG_ACPI_SLEEP to build minimal kernels for just hibernate or just suspend but not both, but today isn't that day. Signed-off-by: Rafael J.
