If stat request fails with something other than -ENOENT (which just
means that we need to copyup), the original object request is never
marked as done and therefore never completed. Fix this by moving the
mark done + complete snippet from rbd_img_obj_parent_read_full() into
rbd_img_obj_exists_callback(). The former remains covered, as the
latter is its only caller (through rbd_img_obj_request_submit()).
