rpc client can not deal with ENOSOCK, so translate it into ENOCONN
commit 5fe46e9d733f19a880ef7e516002bd4c2b833e14 upstream.
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.
