Enforce int type on SNDRV_CTL_ELEM_IFACE_MIXER to fix sparse warning:
> warning: restricted snd_ctl_elem_iface_t degrades to integer
The iface field in the gb_audio_control struct is of type __u8, but the
values stored in it are of type int. So on conversion they are degraded.
Adding (__force int) will enforce them not to be degraded.
