acpi video device enumeration: fix incorrect device list allocation
It didn't allocate space for the final terminating entry,
which caused it to overwrite the next slab entry, which in turn
sometimes ended up being a slab array cache pointer. End result:
total slab cache corruption at a random time afterwards. Very
nasty.
