Subject: RDMA/core: Assign device ifindex before publishing the device
Patch-mainline: v4.20-rc1
Git-commit: 273993509f05623934dda14a56237738149b2906
References: bsc#1103992 FATE#326009

Even though device->ifindex is assigned before adding the device in the
list which is read by netlink flow, it is better to assign rdma device
index before publishing the device in the system to users and clients.
