s390: qeth driver fixes: VLAN hdr, perf stats

From: Ursula Braun <braunu@de.ibm.com>
        - VLAN header reordering did not work on packets
          received through qeth interface in layer 2 mode.
          This caused dhcpcd not to work with VLAN devices.
	- set qeth performance statistics initally inactive
