s390x/pci: refresh fh before disabling aif
Typically we refresh the host fh during CLP enable, however it's possible that the device goes through multiple reset events before the guest performs another CLP enable. Let's handle this for now by refreshing the host handle from vfio before disabling aif.

s390x/pci: enable for load/store interpretation
If the ZPCI_OP ioctl reports that is is available and usable, then the underlying KVM host will enable load/store intepretation for any guest device without a SHM bit in the guest function handle. For a device that will be using interpretation support, ensure the guest function handle matches the host function handle; this value is re-checked every time the guest issues a SET PCI FN to enable the guest device as it is the only opportunity to reflect function handle changes.
By default, unless interpret=off is specified, interpretation support will always be assumed and exploited if the necessary ioctl and features are available on the host kernel. When these are unavailable, we will silently revert to the interception model; this allows existing guest configurations to work unmodified on hosts with and without zPCI interpretation support, allowing QEMU to choose the best support model available.
