RDMA/addr: Keep pointer to netdevice in struct rdma_dev_addr
Keep a pointer to the local (src) netdevice in struct rdma_dev_addr, and copy it in as part of rdma_copy_addr(). Use rdma_translate_ip() in cma_new_conn_id() to reduce some code duplication and also make sure the src_dev member gets set. In a high-availability configuration the netdevice pointer can be used by the RDMA CM to align RDMA sessions to use the same links as the IP stack does under fail-over and route change cases.
