ALSA: firewire: Fix -Wformat-truncation warning for MIDI stream names

The compile warnings at filling MIDI stream name strings are all
false-positive; the number of streams can't go so high.

For suppressing the warning, replace snprintf() with scnprintf().
As stated in the above, truncation doesn't matter.
