When setting bond NS target, we use bond_is_ip6_target_ok() to check
if the address valid. The link local address was wrongly rejected in
bond_changelink(), as most time the user just set the ARP/NS target to
gateway, while the IPv6 gateway is always a link local address when user
set up interface via SLAAC.
So remove the link local addr check when setting bond NS target.
