Subject: zkey: Fix APQN validation routine
From: Ingo Franzki <ifranzki@linux.ibm.com>

Summary: zkey: Support CCA master key change with LUKS2 volumes using paes     
Description: Support the usage of protected key crypto for dm-crypt disks in
             LUKS2 format by providing a tool allowing to re-encipher a 
             secure LUKS2 volume key when the CCA master key is changed

Problem-ID:  SEC1424.1

Upstream-Description:

zkey: Fix APQN validation routine

When a zkey generate or change command is used to associate one
             or multiple APQNs the command succeeds, but no key is generated
             and no APQNs are associated, because the return code returned by
             _keystore_apqn_check() is wrong.
