Rich Lane 610e0a8b62 virtio: use zeroed memory for simple Tx header 
For simple TX the virtio-net header must be zeroed, but it was using memory
that had been initialized with indirect descriptor tables. This resulted in
"unsupported gso type" errors from librte_vhost.

We can use the same memory for every descriptor to save cachelines in the
vswitch.

Fixes: 6dc5de3a ("virtio: use indirect ring elements")
