virtio-serial: Check if virtio queue is ready before consuming data
If a virtio-serial port is removed before the guest comes up and
initialises the virtqueues, qemu exits with the message
Guest moved used index from 0 to 61440
This happens because we try to clear any pending buffers from the
virtqueue.
Ensure the virtqueue is initialised before calling any virtqueue
operations.
