[PATCH] s390: qeth driver fixes

[patch 4/4] s390: qeth driver fixes .

From: Frank Pavlic <pavlic@de.ibm.com>
	- Clear read channel first prior to using ccw_device_set_offline.
	- use QETH_DBF_TEXT instead of QETH_DBF_SPRINTF
	- invoke qeth_halt_channel and qeth_clear_channel for all channels,
	  even if halt/clear for one of the channel fails.
	- enable qeth_arp_query function for GuestLAN devices
