d0cb26ba - [DDP] Fix logging iterations (#64411)

[DDP] Fix logging iterations (#64411) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/64411 These are not actually the training iterations, but are offset by how frequently DDP stats collection actually runs (default being kDDPRuntimeLoggingSampleRate = 100). So with this change, they are actually logged to scuba every: 10, 10 * 100, 40 * 100, etc iterations.
