vhost/net: length miscalculation
commit 8b38694a2dc8b18374310df50174f1e4376d6824
vhost/net: virtio 1.0 byte swap
had this chunk:
- heads[headcount - 1].len += datalen;
+ heads[headcount - 1].len = cpu_to_vhost32(vq, len - datalen);
This adds datalen with the wrong sign, causing guest panics.
Fixes: 8b38694a2dc8b18374310df50174f1e4376d6824
