feature from https://github.com/ceph/ceph/pull/50148 works for 'normal' multipart uploads, but gets stuck in an infinite loop for multipart uploads that only contain a single part

the infinite loop happens here in get_part_obj_state():

  // copy each of the part's stripes into the new manifest. the final call to
  // create_next() uses the starting offset of the next part
  do {
    ++iter;
    gen.create_next(iter.get_ofs() - part_offset);
  } while (iter.get_cur_part_id() == part_num);
