Zhao DongdongandTakashi Iwai c7fa99d30c ALSA: gus: check snd_ctl_new1() return value ...

snd_ctl_new1() can return NULL when memory allocation fails.
snd_gf1_pcm_volume_control() does not check the return value before
dereferencing kctl->id.index, which can lead to a NULL pointer
dereference.

Add a NULL check after snd_ctl_new1() and return -ENOMEM if it fails.
