Using snprintf without a format specifier is potentially risky if
the string device_name contains format specifiers. Replace this with
the safer and more efficient strscpy.
Cleans up clang warning:
drivers/staging/most/sound/sound.c:673:41: warning: format string is not
a string literal (potentially insecure) [-Wformat-security]
