qeth: fix build error caused by VLAN changes

Thanks,

Adrian Bunk reports this build error:

CC drivers/s390/net/qeth_l3_main.o

2654: error: invalid type argument of '->' (have 'int') 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.
