net/smc: Fix lookup of netdev by using ib_device_get_netdev()

The SMC-R variant of the SMC protocol used direct call to function
ib_device_ops.get_netdev() to lookup netdev. As we used mlx5 device
driver to run SMC-R, it failed to find a device, because in mlx5_ib the
internal net device management for retrieving net devices was replaced
by a common interface ib_device_get_netdev() in commit 8d159eb2117b
("RDMA/mlx5: Use IB set_netdev and get_netdev functions").

Since such direct accesses to the internal net device management is not
recommended at all, update the SMC-R code to use proper API
ib_device_get_netdev().
