[pve-devel] [PATCH qemu-server 1/1] fix #6400: pci: allow other pci domains than 0000 for NVIDIA vGPUs

[Dominik Csapak]

when creating or cleaning up NVIDIA vGPUs, we mistakenly assumed a
PCI domain of 0000, but this might be different.

Use 'normalize_pci_id' from PVE::SysFSTools, which handles this already
correctly.
