这里还未确定错误的具体原因（由client导致 或 backend导致）。因此，不能直接对ErrBkWriteRequestByClient进行计数

合理的做法是： 删除line 385/line387，在line 396后增加 :
else {
request.ErrCode = bfe_basic.ErrBkWriteRequestByClient
p.proxyState.ErrBkWriteRequestByClient.Inc(1)
}

建议:
- 把line 44 ErrBkWriteRequestByClient移动到line33之后（代表client类错误）
- 命名修改下 ErrClientReadRequest
