batch commands send error: EOF

[baiwfg2]

Hi. I'm testing tikv with go-ycsb raw kv. And error message batch commands send error: EOF shows up the second time I enter shell commandline and type exit. I think this is a tiny bug. I'll try to fix it in spare time.

one of tikv server log:

[2019/03/18 15:03:14.073 +08:00] [ERROR] [kv.rs:862] ["batch commands error"] [err="RpcFinished(Some(RpcStatus { status: Ok, details: None }))"]

After load phase, same error messages occurred:

em, I guess this is because we don't clean up the batch gRPC connection smoothly, @hicqu
