The series aims at improving virtqueue metadata pointers dereferencing robust.
First patch fixes a real issue reported by our QE. Five next patches validates queue index passed as input of the Vhost API. They are split in 5 patches to ease backporting to LTSes. Last patch is not mandatory now that patch 1 ensures there won't be holes in the array of virtqueue metadata pointers, but I think it is a nice to have anyway.
