net: failover: use IFF_NO_ADDRCONF flag to prevent ipv6 addrconf
Similar to Bonding and Team, to prevent ipv6 addrconf with
IFF_NO_ADDRCONF in slave_dev->priv_flags for slave ports
is also needed in net failover.
Note that dev_open(slave_dev) is called in .slave_register,
which is called after the IFF_NO_ADDRCONF flag is set in
failover_slave_register().
