Issue: Unnecessary record_stream call for backend:cudaMallocAsync
Labels: module: cuda,module: logging,triaged

### 🐛 Describe the bug

When setting `os.environ["PYTORCH_CUDA_ALLOC_CONF"] = "backend:cudaMallocAsync"`, I now see this warning printed 20x per backward pass ( I'm accumulating gradients for 3 batches, and this prints 20x every third batch, so does not appear on forward pass AFAICT):

```[W CUDAMallocAsyncAllocator.cpp:590] Warning: Called record_stream on tensor whose original creation stream matches the recorded stream. This is unnecessary and has no effect. (function recordStream) ```

1. any ideas on how to suppress this warning so it only prints once or never?
2. possible to resolve by removing these unnecessary `record_stream` calls when using `cudaMallocAsync`?

I don't yet have a minimal example, but hope this might make sense to someone. Might be relevant to @eqy (thanks for work on this new backend!)
