[PATCH] ALSA: ice1712: aureon: check CS8415 control allocation

[Ruoyu Wang <ruoyuw560@gmail.com>]

aureon_add_controls() creates CS8415 controls and, for later entries,
adjusts kctl->id.device before adding the control. snd_ctl_new1() can
return NULL, so the device-id update can dereference NULL before the
control core sees the pointer.

Return -ENOMEM when the control allocation fails.
