x86/PCI: default pcibus cpumask to all cpus if it lacks affinity
The early initialization of the pci bus to node mapping leaves all busses with a node id of -1 if it lacks memory affinity. Thus, cpumask_of_pcibus must return all online cpus for such busses. Signed-off-by: David Rientjes <rientjes@google.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
