ALSA: ice1712: Fix the card leak at probe error with the auto-cleanup
snd_ice1712_probe() performs multiple initialization steps after
snd_card_new(), but directly returns on failures from later steps
without releasing the ALSA card, causing resource leaks when
probing fails.
Use snd_devm_card_new() together with scope-based cleanup
via __free(snd_card_unref), and clear the card pointer after
successful registration to keep it alive.
