Check whether stream is closed in BufferedMixin.truncate_w().

Before this, the method was failing later on a closed stream when accessing the
underlying raw stream. It is more consistent and robust to check for a closed
stream earlier.

Starting with the next changeset, closing the stream will set the buffer to
None. Given that the buffer is potentially accessed by truncate_w(), it is
a very good idea to check that the stream is not closed, although it is hard
to make truncate_w() actually access the buffer when the stream is closed
(because closing it will flush the unwritten data from the buffer).

Set buffer of buffered IO classes to None in close().

This helps to reclaim the memory used by the buffer earlier.
