[PATCH] s390: qeth driver fixes

From: Frank Blaschka <Frank.Blaschka@de.ibm.com>
From: Frank Pavlic <fpavlic@de.ibm.com>

        - fix fake_ll during initial device bringup. fake_ll was
	  not active after first start of the device.
	  Problem only occured when qeth was built without IPV6 support.
        - avoid skb usage after invocation of qeth_flush_buffers,
	  because skb might already be freed.
        - remove yet another useless netif_wake_queue in
	  qeth_softsetup_ipv6 since this function is only called
	  when device is going online. In this case card->state will
	  never be in state UP. So let the net_device queue down .
