[Service Fabric] Race condition detected by Parallel Checker in AsyncManualResetEvent

I have [Parallel Checker](https://github.com/blaeser/parallelchecker) installed.
And it tells that this piece of code causes a race condition
``` C#
while (true)
{
var thisTcs = this.taskCompletionSource;

if (!thisTcs.Task.IsCompleted || Interlocked.CompareExchange(ref this.taskCompletionSource, new TaskCompletionSource(), thisTcs) == thisTcs)
{
return;
}
}
```
