[NCCL] Fix NCCL_BLOCKING_WAIT functionality with Async Error Handling (#44411)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/44411
This basically aborts errored NCCL communicators if either blocking
wait or async error handling is enabled. Otherwise we may abort nccl
communicators where neither are enabled, and this may result in subsequent GPU
operations using corrupted data.
