s390/qeth: free netdevice when removing a card
On removal, a qeth card's netdevice is currently not properly freed
because the call chain looks as follows:
qeth_core_remove_device(card)
lx_remove_device(card)
unregister_netdev(card->dev)
card->dev = NULL !!!
qeth_core_free_card(card)
if (card->dev) !!!
free_netdev(card->dev)
Fix it by free'ing the netdev straight after unregistering. This also
fixes the sysfs-driven layer switch case (qeth_dev_layer2_store()),
where the need to free the current netdevice was not considered at all.
Note that free_netdev() takes care of the netif_napi_del() for us too.
Fixes: 4a71df50047f ("qeth: new qeth device driver")
