The result of ceph_copy_from_page_vector() is simply the length argument it is provided. This is called by rbd_obj_method_sync(), which returns the result if it's non-negative. But we always either ignore or overwrite that return value. So explicitly ignore what's returned by the copy function, and have rbd_obj_method_sync() always return either a negative errno or 0. We also return the result of ceph_copy_from_page_vector() in rbd_obj_read_sync(). There we still want to return the number of bytes transferred, but we can use the value we already have in hand rather than what ceph_copy_from_page_vector() provides.
