Takashi Iwai caa47cc639 tty: nozomi: Use scnprintf() for avoiding potential buffer overflow 
Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit.  Fix it by replacing with scnprintf().

Also rewrite the code in a standard if-form instead of ugly
conditional operators.
