  lib-dcrypt: Don't finalize encryption on o_stream_flush()

For example the default o_stream_uncork() implementation enforces flushing
and it's probably better not to change that. In general there's really no
reason to perform the finalization at flush when the stream can't be written
to anymore (whereas lib-compression ostreams allow writes after flushes).
