Description of problem:

In a multipart upload, when resending the first part of the object, and potentially other parts of the objects, the manifest created is broken.


Version-Release number of selected component (if applicable):


How reproducible:

always

Steps to Reproduce:
1. Create multipart upload
2. Resend the first part of the object
3. Finish multipart upload
4. radosgw-admin object stat --bucket=<bucket> --object=<object>

Actual results:

Manifest is broken, the prefix defines the first part correctly, but following parts do not hold override_prefix as needed.


Expected results:

Prefix should note the first object (prefix) appropriately, and subsequent parts should have correct override_prefix.
