[sheepdog] [PATCH v2 08/11] group: add node to sockfd_cache as early as possible

[Liu Yuan]

get_vdis will try to connect to all the nodes include joining node, so before
calling get_vdis, we'd better add joining node in the sockfd cache. This is not
a fatal problem and sockfd cache can actually sort it out with the old code, but
this patch will safe us unnecessary revalidating node after grab failure.
