IB/core: Allow vlan link local address based RoCE GIDs
IPv6 link local address for a VLAN netdevice has nothing to do with its resemblance with the default GID, because VLAN link local GID is in different layer 2 domain. Now that RoCE MAD packet processing and route resolution consider the right GID index, there is no need for an unnecessary check which prevents the addition of vlan based IPv6 link local GIDs.
