  vhost: disable metadata prefetch optimization (2019-07-26 07:49:29 -0400)

----------------------------------------------------------------
virtio, vhost: bugfixes

Fixes in the iommu and balloon devices.
Disable the meta-data optimization for now - I hope we can get it fixed
shortly, but there's no point in making users suffer crashes while we
are working on that.
