virtio-devices: vhost-user: Enable correct queue indexes

Browse Source 
Rather than relying on the amount of queues to enable or disable the
queue that have been activated, we rely on the actual queue indexes
provided through the tuple including the queue index, the Queue and the
EventFd. By storing the list of indexes, we simplify the code and also
make it more accurate in case some queues aren't activated.
