qeth: repair crash in qeth_l3_vlan_rx_kill_vid()

Browse source

commit eabfbe6230 upstream.

Commit efc73f4b "net: Fix memory leak - vlan_info struct" adds deletion of
VLAN 0 for devices with feature NETIF_F_HW_VLAN_FILTER. For driver
qeth these are the layer 3 devices. Usually there exists no
separate vlan net_device for VLAN 0. Thus the qeth functions
qeth_l3_free_vlan_addresses4() and qeth_l3_free_vlan_addresses6()
require an extra checking if function __vlan_find_dev_deep()
returns with a net_device.
