There are some early returns in ``odb_source_loose_read_object_info()` in cases where we don't have to open the loose object. These return paths do not set `struct object_info::whence` to `OI_LOOSE` though, so it becomes impossible for the caller to tell the format of such an object.
Nobody seems to care about this right now, but it's a bug waiting to happen. Fix this by always setting `whence` on success.
