[sheepdog] [PATCH stable-0.9 6/7] dog: referencing uninitialized buffer during cluster format

[Hitoshi Mitake]

From: Saeki Masaki <saeki.masaki at po.ntts.co.jp>

when executing dog cluster format,
by referring to the memory area that is not initialized
update_node_list() was an unintended behavior.
