Julian Wiedmann 049fee28bb s390/qeth: fix error handling in adapter command callbacks
[ Upstream commit 686c97ee29 ]

Make sure to check both return code fields before(!) processing the
command response. Otherwise we risk operating on invalid data.

This matches an earlier fix for SETASSPARMS commands, see
commit ad3cbf6133 ("s390/qeth: fix error handling in checksum cmd callback").
