RoCEv1 does not use the IPv6 stack to resolve the link local DGID since it uses GID address. It forms the DMAC directly from the DGID. The code became confused and also tried to use this bypass for RoCEv2 packets, however RoCEv2 always uses a IP address in the GID and must always use ARP or neighbor discovery to get the DMAC address. Now that rdma_addr_find_l2_eth_by_grh() supports resolving link local address to find destination mac address, lets make use of it. This aligns it to how the rest of the IPv6 stack resolves link local destination IPv6 address.
