ASoC: core: Make snd_soc_unregister_card() return void

The function snd_soc_unregister_card() returned 0 unconditionally and most
callers don't care to check the return value. Make it return void and
adapt the callers that didn't ignore the return value before.

This is a preparation for making platform remove callbacks return void.
