para_filter: Call proper ->free_config method on shutdown.

Currently we just free the conf struct. For some filters this not
enough to deallocate all resources and therefore results in a memory
leak.  This leak is not serious though, since it does not affect
para_audiod, and para_filter is about to exit anyway at this point.

Fix it anyway.
