[PATCH] s390: qeth driver fixes

From: Peter Tiedemann <ptiedem@de.ibm.com>
From: Frank Pavlic <pavlic@de.ibm.com>
	minor qeth fixes:
	- free old skb in qeth_realloc_headroom after duplicating skb
	- disable IPV6 support for Hipersockets devices
	- call ccw_device_set_offline on every channel regardless
	  of the return value of the prior ccw_device_set_offline calls
	- allocate qdio structures in DMA-area
	- schedule recovery of appropriate card
	  when cable has been inserted again.
	- add missing initialization of card->lock
	- write sequence number in skb->cb for SNA protocol which
	  requires strictly serialized packets.
