Li Feng initially reported segmentation fault in rte_vhost_vring_call()
because of not checking the virtqueue metadata can be accessed.

This should be achieved by checking the access_ok status field of
the virtqueue.

This series also takes the opportunity to fix the other APIs.
This is split in multiple patches to ease LTS maintainers backports,
but could be squashed if preferred.

Maxime Coquelin (7):
  vhost: fix missing vring call check on virtqueue access
  vhost: fix missing check on virtqueue access
  vhost: fix checking virtqueue access when notifying guest
  vhost: fix check on virtqueue access in async registration
  vhost: Fix check on virtqueue access in in-flight getter
  vhost: fix missing lock protection in power monitor API
  vhost: fix checking virtqueue access ins stats API
