Public bug reported:
SRU Justification
[Impact]
When kernel boots with a NUMA topology with some NUMA nodes offline, the PCI
driver should only set an online NUMA node on the device. This can happen
during KDUMP where some NUMA nodes are not made online by the KDUMP kernel.
This patch also fixes the case where kernel is booting with "numa=off".
Fixes: 999dd956d838 ("PCI: hv: Add support for protocol 1.3 and support
PCI_BUS_RELATIONS2")
[Test Case]
Microsoft tested.
[Where things could go wrong]
NUMA node assignments could be wrong.
