kernel/cpu.c: don't use snprintf() for sysfs attrs As per the documentation (Documentation/filesystems/sysfs.rst), snprintf() should not be used for formatting values returned by sysfs. In all of these cases, sprintf() suffices as we know that the formatted strings will be less than PAGE_SIZE in length. Issue identified by Coccinelle.
