Stefan Hajnoczi ec55da1924 virtio: handle virtqueue_map_desc() errors ...

Errors can occur during virtqueue_pop(), especially in
virtqueue_map_desc().  In order to handle this we must unmap iov[]
before returning NULL.  The caller will consider the virtqueue empty and
the virtio_error() call will have marked the device broken.
