This series is again preliminray work to ease packed ring
layout integration.

Main changes are using vector buffres also in the dequeue
path, and perform IOVA to HVA translation at vectors fill
time.

I still have to run more benchmarks, but PVP benchmarks does
not show performance changes.

Good thing is that it saves ~140 further lines.

Maxime Coquelin (7):
  vhost: use shadow used ring in dequeue path
  vhost: make gpa to hpa failure an error
  vhost: use buffer vectors in dequeue path
  vhost: translate iovas at vectors fill time
  vhost: improve prefetching in dequeue path
  vhost: prefetch first descriptor in dequeue path
  vhost: improve prefetching in enqueue path
