Slimbus streams are first prepared and then enabled, so the cleanup path should reverse it. The unprepare sets stream->num_ports to 0 and frees the stream->ports. Calling disable after unprepare was not really effective (channels was not deactivated) and could lead to further issues due to making transfers on unprepared stream.
