audioconvert: be more careful when clearing buffers

Browse source 
clean_convert() removes the internally negotiated formats but
it does not set the format (or buffers) of the externally visible
ports. Therefore, don't clear the buffers_set flags.

Instead, clear the buffers_set flag when we explicitly reconfigure
the ports, when we also clear the format.

Also clear the port buffers when we set a NULL format.

Fixes #178
