Virtio 0.9 implementation was limited to the maximum virtqueue size of MAX_QUEUE_NUM and the virtio-net driver would fail to initialize on hosts exceeding this limit. This commit lifts the restriction by allocating the queue memory based on the actual queue size instead of using a fixed maximum. Note that virtio 1.0 still uses the MAX_QUEUE_NUM constant to cap the size (unfortunately this functionality is not available in virtio 0.9).
