selftests: rtnetlink: add addresses with fixed life time
This exercises kernel code path that deal with addresses that have a limited lifetime. Without previous fix, this triggers following crash on net-next: BUG: KASAN: null-ptr-deref in check_lifetime+0x403/0x670 Read of size 8 at addr 0000000000000010 by task kworker [..] Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
