selftests: forwarding: Delete IPv6 address at the end

[ Upstream commit 65cb13986229cec02635a1ecbcd1e2dd18353201 ]

When creating the second host in h2_create(), two addresses are assigned
to the interface, but only one is deleted. When running the test twice
in a row the following error is observed:

$ ./router_bridge_vlan.sh
TEST: ping                                                          [ OK ]
TEST: ping6                                                         [ OK ]
TEST: vlan                                                          [ OK ]
$ ./router_bridge_vlan.sh
RTNETLINK answers: File exists
TEST: ping                                                          [ OK ]
TEST: ping6                                                         [ OK ]
TEST: vlan                                                          [ OK ]

Fix this by deleting the address during cleanup.
