ipfilter: Avoid more null if-then-else blocks

Browse source 
As in 73db3b64f1, when WITHOUT_INET6 is selected, null if-then-else
blocks are generated because #if statements are incorrectly placed.
Moving the #if statements reduces unnecessary runtime comparisons or
compiler optimizations.

(cherry picked from commit 130df64793)
