vfio-pci/zdev: add function handle to clp base capability
The function handle is a system-wide unique identifier for a zPCI
device. With zPCI instruction interpretation, the host will no
longer be executing the zPCI instructions on behalf of the guest.
As a result, the guest needs to use the real function handle in
order for firmware to associate the instruction with the proper
PCI function. Let's provide that handle to the guest.
