Subject: [PATCH iproute2 net-next] ip neigh: allow flush FAILED neighbour entry

After upstream commit 5071034e4af7 ('neigh: Really delete an arp/neigh entry
on "ip neigh delete" or "arp -d"'), we could delete a single FAILED neighbour
entry now. But `ip neigh flush` still skip the FAILED entry.

Let's remove this filter so we can also flush FAILED entry.
