The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature.  Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().

This patch fixes it by calling snd_card_free() on the error from the
probe callback using a new helper function.
