ASoC: SOF: topology: cleanup dailinks on widget unload
We set the cpu_dai capture_ or playback_widget on widget_ready but
never clear them, which leads to failures when unloading/reloading a
topology in modprobe/rmmod tests
BugLink: https://github.com/thesofproject/linux/issues/3535
Fixes: 311ce4fe7637 ("ASoC: SOF: Add support for loading topologies")
