Subject: [PATCH net-next] selftests: forwarding: lib.sh: ignore "Address not found"

From: Geliang Tang <tanggeliang@...inos.cn>

So many "Address not found" messages occur at the end of forwarding tests
when using "ip address del" command for an invalid address:

TEST: FDB limits interacting with FDB type local                    [ OK ]
Error: ipv4: Address not found.

... ...
TEST: IGMPv3 S,G port entry automatic add to a *,G port             [ OK ]
Error: ipv4: Address not found.
Error: ipv6: address not found.

... ...
TEST: Isolated port flooding                                        [ OK ]
Error: ipv4: Address not found.
Error: ipv6: address not found.

... ...
TEST: Externally learned FDB entry - ageing & roaming               [ OK ]
Error: ipv4: Address not found.
Error: ipv6: address not found.

This patch gnores these messages and redirects them to /dev/null in
__addr_add_del().
