Review Comment:
Sorry for not make it clear in this issue.
The `check` means sending `azfile_get_path_properties` call before calling
`azfile_create_dir` to avoid extra API calls.
Take `a/b/c` as an example:
- Check if `a/b/` exist -> No
- Check if `a/` exist -> No
- Create `a/`
- Create `a/b/`
In the best case: if `a/b/` exists, we can avoid two APIs of create_dir.
