[SRU][N][PATCH 3/4] netdevsim: fix rtnetlink.sh selftest

[Alessio Faina]

From: David Wei <dw at davidwei.uk>

I cleared IFF_NOARP flag from netdevsim dev->flags in order to support
skb forwarding. This breaks the rtnetlink.sh selftest
kci_test_ipsec_offload() test because ipsec does not connect to peers it
cannot transmit to.

Fix the issue by adding a neigh entry manually. ipsec_offload test now
successfully pass.
