impl-port: improve IO_Buffers management on ports

Browse source 
Make sure we clear IO_Buffers on the port and mixer before we clear the
buffers or the format. The IO_Buffer is used to check if the port should
be processed or not and its update is synchronized with the data-thread.

Set IO_Buffers on the mixer and node only after we have configured the
buffers on the node.

See #4094
