s390/qeth: get vnicc sub-cmd type from reply data
When processing the reply for a vnicc cmd, there's no need to remember which specific sub-cmd type we initially sent. The reply itself contains all the needed information. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
