Fix build errors when CONFIG_KVM=m:
s390-linux-ld: drivers/vfio/pci/vfio_pci_zdev.o: in function `vfio_pci_zdev_open_device': vfio_pci_zdev.c:(.text+0x242): undefined reference to `kvm_s390_pci_register_kvm' s390-linux-ld: drivers/vfio/pci/vfio_pci_zdev.o: in function `vfio_pci_zdev_close_device': vfio_pci_zdev.c:(.text+0x296): undefined reference to `kvm_s390_pci_unregister_kvm'
Having a bool Kconfig symbol depend on a tristate symbol can often lead to problems like this.
