From: luoxuanqiang <luoxuanqiang@xxxxxxxxxx>
When adding the "netdevice ref tracker" mechanism to ib_port_data, the
dev_hold() in ib_device_get_netdev() was missed, which may cause false
alarms of ref leak. Replace dev_hold() with netdev_hold() to fix it.
Fixes: 09f530f0c6d6 ("RDMA: Add netdevice_tracker to ib_device_set_netdev()")
