ALSA: xen: Fix -Wformat-truncation warning
The compile warning with -Wformat-truncation at xen_snd_front_cfg_card() is false-positive; the loop can be only for SNDRV_PCM_DEVICES which is at most 32. For suppressing the warning, replace snprintf() with scnprintf(). As stated in the above, truncation doesn't matter.
