cpuidle: sysfs: Fix the overlap for showing available governors
When showing the available governors, it's "%s " in scnprintf(), not "%s", so if the governor name has 15 characters, it will overlap with the later one, fix it by adding one more for the size. While we are at it, fix the minor coding style issue and remove the "/sizeof(char)" since sizeof(char) always equals 1.
