[patch 1/3] s390: some minor qeth driver fixes

From: Frank Pavlic <pavlic@de.ibm.com>
	- let's have just one function for both ,input and output queue
	  to check qdio errors
	- add /proc/s390dbf/qeth_qerr entries for outbound processing
	- check removed for layer2 device in qeth_add_multicast_ipv6
	- NULL pointer dereference with bonding and VLAN device fixed
	- minimum length check for portname fixed

Signed-off-by: Frank Pavlic <pavlic@de.ibm.com>
