ASoC: codecs: wcd939x: fix OF node leaks on probe failure

The component match entry release function will drop the references
taken while looking up the soundwire OF nodes when the platform device
is unbound.

Drop the additional references taken to avoid leaking them on probe
failure (e.g. probe deferral) and on driver unbind.
