  virtio-vdpa: Drop redundant conversion to bool (2025-10-01 07:24:55 -0400)

----------------------------------------------------------------
virtio,vhost: fixes, cleanups

Just fixes and cleanups this time around.  The mapping cleanups are
preparing the ground for new features, though.
In order patches were almost there but I feel they didn't
spend enough time in next yet.
