[PATCH ipset 2/3] tests: hash:net,iface: timed-out entries must be ignored

[Florian Westphal <fw@strlen.de>]

When a timed-out entry in a `hash:net,iface` set expires, it should no
longer affect matching: lookups must behave as if the entry had already
been reaped by GC.

As-is, the expired entry continues to shadow the broader one until GC
removes the entry from the set, creating a window where matching is
inconsistent with the entry's logical state.

Signed-off-by: Florian Westphal <fw@strlen.de>

 Fails on main, but not on rhashtable v8 patches.
