[PATCH net-next] net/smc: use new helper to get the netdev associated to an ibdev

[Wen Gu <guwen@linux.alibaba.com>]

Patch [1] provides common interfaces to store and get net devices
associated to an IB device port and removes the ops->get_netdev()
callback of mlx5 driver. So use the new interface in smc.

[1]: 8d159eb2117b ("RDMA/mlx5: Use IB set_netdev and get_netdev functions")
