Karl Heiss 3d2f497e4d bonding: Prevent IPv6 link local address on enslaved devices 
[ Upstream commit 03d84a5f83 ]

Commit 1f718f0f4f ("bonding: populate neighbour's private on enslave")
undoes the fix provided by commit c2edacf80e ("bonding / ipv6: no addrconf
for slaves separately from master") by effectively setting the slave flag
after the slave has been opened.  If the slave comes up quickly enough, it
will go through the IPv6 addrconf before the slave flag has been set and
will get a link local IPv6 address.

In order to ensure that addrconf knows to ignore the slave devices on state
change, set IFF_SLAVE before dev_open() during bonding enslavement.
