Matthew Rosato 189e7d876e KVM: s390: pci: register pci hooks without interpretation 
The kvm registration hooks must be registered even if the facilities
necessary for zPCI interpretation are unavailable, as vfio-pci-zdev will
expect to use the hooks regardless.
This fixes an issue where vfio-pci-zdev will fail its open function
because of a missing kvm_register when running on hardware that does not
support zPCI interpretation.

Fixes: ca922fecda ("KVM: s390: pci: Hook to access KVM lowlevel from VFIO")
