ipv6: fix refcnt problem related to POSTDAD state
After running this bonding setup script
modprobe bonding miimon=100 mode=0 max_bonds=1
ifconfig bond0 10.1.1.1/16
ifenslave bond0 eth1
ifenslave bond0 eth3
on s390 with qeth-driven slaves, modprobe -r fails with this message
unregister_netdevice: waiting for bond0 to become free. Usage count = 1
due to twice detection of duplicate address.
Problem is caused by a missing decrease of ifp->refcnt in addrconf_dad_failure.
An extra call of in6_ifa_put(ifp) solves it.
Problem has been introduced with commit f2344a131bccdbfc5338e17fa71a807dee7944fa.
