[PATCH][V3]rpc client can not deal with ENOSOCK, so translate it into ENOCONN

[Bian Naimeng <biannm@cn.fujitsu.com>]

Sorry, I need remove the unused lable "out:".

---

If NFSv4 client send a request before connect, or the old connection was broken
because a ETIMEOUT error catched by call_status, ->send_request will return
ENOSOCK, but rpc layer can not deal with it, so make sure ->send_request can
translate ENOSOCK into ENOCONN.
