[sheepdog] [PATCH stable-0.8 3/3] dog: use nr_copies of inode object instead of command line parameter

[Hitoshi Mitake]

From: Hitoshi Mitake <mitake.hitoshi at lab.ntt.co.jp>

Current "dog vdi clone" has a possibility of creating clone volume
which has a different replica number from its original volume when it
receives -c option. This patch forbid such a situation by letting
vdi_clone() use inode->nr_copies instead of vdi_cmd_data.nr_copies
(the variable which holds a value passed with -c option).
