pointers to an integer via uintptr_t.
Fix an apparent bug that caused a compile failure.
ieee80211_iterate_nodes() takes ic->ic_sta as its first argument on the
onoe module. It had just 'ic' here in the same context, which was a
mismatched argument.
of a sizeof, need to use %z to get the correct type on all our platforms.
Also, convert integers<->pointers via uintptr_t.
(I think Sam's instructions were for me to commit this. If I
misunderstood, then I apologize in advance.)
