This patch series fixes the issue with unplug/replug of a port in virtio
console device, which fails with an error "Error allocating inbufs\n".

Patch 2 makes virtio packed ring code compatible with virtio split ring.
Tested the packed ring code with the qemu virtio 1.1 device code posted
here [1].
