2dd172c5b6 dragonball: Add the pci bus support for virtio-blk 
Added support for PCI buses for virtio-blk devices. This commit adds
support for PCI buses for both cold-plugged and hot-plugged
virtio-blk devices. Furthermore, during hot-plugging, support is added for
synchronous waiting for hot-plug completion. This ensures that multiple devices
can be hot-plugged successfully without causing upcall busy errors.

71b6acfd7e dragonball: vsock: support single descriptor 
Since kernel v6.3 the vsock packet is not split over two descriptors and
is instead included in a single one.

Therefore, we currently decide the specific method of obtaining
BufWrapper based on the length of descriptor.
