[PATCH 7/9] s390: qeth driver fixes [4/6]

From: Frank Pavlic <fpavlic@de.ibm.com>
	- fix kernel crash due to race,
	  set card->state to SOFTSETUP after
	  card and card->dev are initialized properly.
	- remove CONFIG_QETH_PERF_STATS, use sysfs attribute instead,
	  as we want to have the ability to turn on/off the
	  statistics at runtime.
