s390/zcrypt: fix wrong offset index for APKA master key valid state
[ Upstream commit 8617bb7 ] Tests showed a mismatch between what the CCA tool reports about the APKA master key state and what's displayed by the zcrypt dd in sysfs. After some investigation, we found out that the documentation which was the source for the zcrypt dd implementation lacks the listing of 3 fields. So this patch now moves the evaluation of the APKA master key state to the correct offset.
