Fix TensorPipe submodule (#42789)
Summary:
Not sure what happened, but possibly I landed a PR on PyTorch which updated the TensorPipe submodule to a commit hash of a *PR* of TensorPipe. Now that the latter PR has been merged though that same commit has a different hash. The commit referenced by PyTorch, therefore, has become orphaned. This is causing some issues.
Hence here I am updating the commit, which however does not change a single line of code.
