lorry li acbaf16fb7 Fix a random dead lock when shut down http manager. ...

Reason: Currently when shutdown and flush in http manager, it gives up and cancels remaining requests after waiting a short period. When cancel, it holds the RequestLock, and in FHttpRequestCommon::CancelRequest, it tries to access HttpTaskTimerHandleCriticalSection to stop activity timer. In the mean time, the request itself could be in activity or total timeout callback, which is holding the HttpTaskTimerHandleCriticalSection, and trying to AbortRequest which will try to access RequstLock in HttpManager.IsValidRequest.
