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.
Fixes: 9c312e79d6af ("selinux: Delete an unnecessary variable initialisation in range_read()")
