Fix: don't modify S3 file name when not using prefix_path (#7152)
### What problem does this PR solve?

Hello, I encountered a problem when trying to use a S3 backend
(seaweedfs) for storage in RAGFlow: when calling
`STORAGE_IMPL.get("bucket", "key")`, the actual request sent to S3 is
`bucket/bucket/key`, causing a `NoSuchKey` error.

I compared the code in `s3_conn.py` to `minio_conn.py` and
`oss_conn.py`, then decided to remove the `else` branch in
`use_prefix_path` method, and it works. I didn't configure `prefix_path`
or `bucket` in `s3` section of the `service_conf.yaml`.

I think this is a bug, but not sure.
