selinux: Fix an uninitialized variable bug
We removed this initialization as a cleanup but it is probably required. The concern is that "nel" can be zero. I'm not an expert on SELinux code but I think it looks possible to write an SELinux policy which triggers this bug. GCC doesn't catch this, but my static checker does.
