Takashi Iwai 57860a80f0 ALSA: 6fire: Release resources at card release ...

[ Upstream commit a0810c3d6d ]

The current 6fire code tries to release the resources right after the
call of usb6fire_chip_abort().  But at this moment, the card object
might be still in use (as we're calling snd_card_free_when_closed()).

For avoid potential UAFs, move the release of resources to the card's
private_free instead of the manual call of usb6fire_chip_destroy() at
the USB disconnect callback.
