network: roll back ipv6ll_address on link_ipv6ll_gained() failure

If link_ipv6ll_gained() fails after ipv6ll_address is set, the address
remains non-null and the null-guard in address_update() never triggers
again, permanently suppressing SLAAC, DHCPv6 and RA on that link.

Clear ipv6ll_address on the failure path so the guard can fire when
the address is re-announced.
