If a stream is stopped, or if a USERPTR/DMABUF buffer is queued backed by a different user address or dmabuf fd, then the timestamp should be skipped by vb2_find_timestamp since the memory it refers to is no longer valid. So keep track of a 'copied_timestamp' state: it is set when the timestamp is copied from an output to a capture buffer, and is cleared when it is no longer valid.
