25f36795 - Replace hasattr with getattr in pytorch/benchmark/torchbenchmark/util/distributed/core_model/trainer.py

Replace hasattr with getattr in pytorch/benchmark/torchbenchmark/util/distributed/core_model/trainer.py Summary: The pattern ``` X.Y if hasattr(X, "Y") else Z ``` can be replaced with ``` getattr(X, "Y", Z) ``` The [getattr](https://www.w3schools.com/python/ref_func_getattr.asp) function gives more succinct code than the [hasattr](https://www.w3schools.com/python/ref_func_hasattr.asp) function. Please use it when appropriate. **This diff is very low risk.
