SELinux: remove needless sel_div function
I'm not really sure what the idea behind the sel_div function is, but it's
useless. Since a and b are both unsigned, it's impossible for a % b < 0.
That means that part of the function never does anything. Thus it's just a
normal /. Just do that instead. I don't even understand what that operation
was supposed to mean in the signed case however....
If it was signed:
sel_div(-2, 4) == ((-2 / 4) - ((-2 % 4) < 0))
((0) - ((-2) < 0))
((0) - (1))
(-1)
What actually happens:
sel_div(-2, 4) == ((18446744073709551614 / 4) - ((18446744073709551614 % 4) < 0))
((4611686018427387903) - ((2 < 0))
(4611686018427387903 - 0)
((unsigned int)4611686018427387903)
(4294967295)
Neither makes a whole ton of sense to me. So I'm getting rid of the
function entirely.
