After 'commit 876fd05ddbae03166e7037fca957b55bb3be6594
("ipv6: don't disable interface if last ipv6 address is removed")'
it is not clearing ipv6 interface configurations(routes, neighbours,
etc) when last ipv6 address of interface is removed.
This patch will call addrconf_ifdown when last ipv6 address of
interface is removed to clear ipv6 interface configurations. This will
not delete /proc/sys/net/ipv6/conf/<interface> directory.
