rbd: move rbd_dev_refresh() definition
Move rbd_dev_refresh() definition further down to avoid having to move struct parent_image_info definition in the next commit. This spares some forward declarations too. Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Dongsheng Yang <dongsheng.yang@easystack.cn>
