Alexandru Matei c3f1c3ee3d virtio-devices: save pci configuration capability state in snapshot ...

When restoring a VM, the VirtioPciCfgCapInfo struct is not properly
initialized. All fields are 0, including the offset where the
capabibility starts. Hence, when you read a PCI configuration register
in the range [0..length(VirtioPciCfgCap)] you get the value 0 instead of
the actual register contents.

Linux rescans the whole PCI bus when adding a new device. It reads the
values vendor_id and device_id for every device. Because these are
stored at offset 0 in pci configuration space, their value is 0 for
existing devices.  As such, Linux considers that the devices have been
unplugged and it removes them from the system.

Fixes: #6265
