PCI: Check the node argument passed to cpumask_of_node
Commit e0cd516 "PCI: derive nearby CPUs from device's instead of bus'
NUMA information" causes an null pointer dereference when reading from
the sysfs attributes local_cpu* on Intel machines with no ACPI NUMA
proximity info, since dev->numa_node gets set to -1 for all PCI devices,
which then gets passed to cpumask_of_node.
Add a check to prevent this.
