Accepts as valid responses to staged requests.

Before these changes the request had to be marked as written in order to
interpret incoming responses as belonging to that request. On fast
networks however, like on localhost and underload the responses might
arrive before the write operation completed.

+* Fixes [issue 170](https://github.com/boostorg/redis/issues/170).
+  Under load and on low-latency networks it is possible to start
