network driver fixes:
- Use SET_NETDEV_DEV to create the link from the network device to the
physical device. Remove link from physical to network device.
- Remove some unnecessary casts in netiucv.
- Add missing strings to dev_stat_names & dev_event_names.
- Add missing preempt_disable/preempt_enable pairs in iucv.
