virtio-devices: Handle virtio queues interrupts from transport layer

Instead of relying on the virtio-queue crate to store the information
about the MSI-X vectors for each queue, we handle this directly from the
PCI transport layer.

This is the first step in getting closer to the upstream version of
virtio-queue so that we can eventually move fully to the upstream
version.
