[PATCH] s390: qeth driver cleanups

[patch 3/6] s390: qeth driver cleanups

From: Ursula Braun <braunu@de.ibm.com>
	- code analyzing tool BEAM has found some unreachable
	  and unnecessary statements and also conditions
	  which are always true.
	- removed some useless MII code since OSA card will never
	  allow to set such values.
