qeth: delete napi struct when removing a qeth device

Browse source

commit 7831b4ff0d upstream.

A qeth_card contains a napi_struct linked to the net_device during
device probing. This struct must be deleted when removing the qeth
device, otherwise Panic on oops can occur when qeth devices are
repeatedly removed and added.
