bus/pci: ignore missing NUMA node on Windows

On older processors, NUMA isn't bound to PCIe locality.
those cases return ERROR_NOT_FOUND in response to the
SetupDiGetDevicePropertyW call with DEVPKEY_Device_Numa_Node
attribute.

This error fails the probe process for the PCIe device.
this commit will ignore such failure and will set the
numa_node to 0.
