  lib-dcrypt: Allow flushing ostream multiple times.

The first time flushes the encryption and the following times just flush the
parent stream.

  Log Message:
  -----------
  Calling i_stream_next_line() on a chain stream would sometimes erroneously use the stream->w_buffer.

It used the wrong check to assess whether the w_buffer is usable.
The chain stream only uses the w_buffer when partial stream data needs to be merged. Otherwise, a parent stream's buffer is used directly. However, this does not mean that w_buffer will be NULL in that case, which is what i_stream_next_line() assumed.
