qeth: delete napi struct when removing a qeth device
[ Upstream commit 7831b4ff0d926e0deeaabef9db8800ed069a2757 ]
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.
Fixes: a1c3ed4c9ca ("qeth: NAPI support for l2 and l3 discipline")
