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.
