[PATCH v3 7/7] selinux: use unsigned iterator in nlmsgtab code

[Christian Göttsche <cgzones@xxxxxxxxxxxxxx>]

Use an unsigned type as loop iterator.

Signed-off-by: Christian Göttsche <cgzones@xxxxxxxxxxxxxx>
---
v3: use unsigned int instead of u32 since the loop bound is known at
    compile time and small (<100)
v2: avoid declarations in init-clauses of for loops
