Del ipv6 addr on close of linux tun interface
When a linux tun interface is closed (e.g. on disconnect)
an optional ipv6 addr that was previously set is deleted now.
Without this patch a later reconnect could fail with
'Linux ip -6 addr add failed: external program exited with error status: 2'
and openvpn would exit.
This is mainly relevant for persistant tun devices (staying around
after openvpn exits) but can also happen at reconnect.
If addresses are *supposed* to stay around on openvpn exit, run
openvpn with --ifconfig-noexec and configure IPv4/IPv6 addresses
manually before openvpn starts (or using an --up script).
