ASoC: SOF: hda-sdw-bpt: mark bpt_stream->link_locked

Currently, the BPT stream will not run with other streams. So there is
no issue we don't mark bpt_stream->link_locked. But we will support
the BRA and audio streams run simultaneously. Therefore, marking
link_locked is required to prevent the link being used by different
streams.
