Commit c2261dd76b54 ("RDMA/device: Add ib_device_set_netdev() as an alternative to get_netdev") introduced an API ib_device_get_netdev. The SMC-R variant of the SMC protocol continued to use the old API ib_device_ops.get_netdev() to lookup netdev. As this commit 8d159eb2117b ("RDMA/mlx5: Use IB set_netdev and get_netdev functions") removed the get_netdev callback from mlx5_ib_dev_common_roce_ops, calling ib_device_ops.get_netdev didn't work any more at least by using a mlx5 device driver. Thus, using ib_device_set_netdev() now became mandatory. Replace ib_device_ops.get_netdev() with ib_device_get_netdev().
