xen/pci: Fix compiler error when CONFIG_XEN_PRIVILEGED_GUEST is not set.

If we have CONFIG_XEN and the other parameters to build an
Linux kernel that is non-privileged, the xen_[find|register|unregister]_
device_domain_owner functions should not be compiled. They should
use the nops defined in arch/x86/include/asm/xen/pci.h instead.

This fixes:

arch/x86/pci/xen.c:496: error: redefinition of ‘xen_find_device_domain_owner’
arch/x86/include/asm/xen/pci.h:25: note: previous definition of ‘xen_find_device_domain_owner’ was here
arch/x86/pci/xen.c:510: error: redefinition of ‘xen_register_device_domain_owner’
arch/x86/include/asm/xen/pci.h:29: note: previous definition of ‘xen_register_device_domain_owner’ was here
arch/x86/pci/xen.c:532: error: redefinition of ‘xen_unregister_device_domain_owner’
arch/x86/include/asm/xen/pci.h:34: note: previous definition of ‘xen_unregister_device_domain_owner’ was here
