The intention appears to be to invalidate the tag (its used
later on again if present), so that doesn't look correct.

qeth: fix build error caused by VLAN changes

Adrian Bunk reports this build error:

make[3]: *** [drivers/s390/net/qeth_l3_main.o] Error 1

The intention of the driver appears to be to invalidate the VLAN tag.
Change it to set skb->vlan_tci to zero, which has the same effect.
