[sheepdog] [PATCH v2 1/2] sheep: remove invalid usage of current_vnode_info

[Hitoshi Mitake]

The variable current_vnode_info should be treated with the functions
get_vnode_info() and put_vnode_info(). But some part of group.c didn't
follow this rule. This patch fixes the clear problem in
update_cluster_info(), sd_leave_handler() and kick_node_recover().
