ASoC: topology: Properly unregister DAI on removal

Browse Source 
commit fc4cb1e15f upstream.

DAIs need to be removed when topology unload function is called (usually
done when component is being removed). We can't do this when device is
being removed, as structures we operate on when removing DAI can already
be freed.
