Subject: s390x/pci: restore missing Query PCI Function CLP data

Git-commit: 403af209db8c030ed1e000640cd3cd80c6882883
References: bsc#1183372

Some CLP response data was accidentally dropped when fixing endianness
issues with the Query PCI Function CLP response.  All of these values are
sent as 0s to the guest for emulated devices, so the impact is only
observed on passthrough devices.
