libqos: add qvirtqueue_cleanup()
qvirtqueue_setup() allocates the vring and virtqueue state. So far there has been no function to free it. Callers have been using guest_free() for the vring but forgot to free the QVirtQueue state. This patch solves the memory leak by introducing qvirtqueue_cleanup(). Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
