Following up on my previous work to make virtio-mem consume multiple memslots dynamically [1] that requires precise accounting between used vs. reserved memslots, I realized that vhost makes this extra hard by filtering out some memory region sections (so they don't consume a memslot) in the vhost-user case, which messes up the whole memslot accounting.
This series fixes what I found to be broken and prepares for more work on [1]. Further, it cleanes up the merge checks that I consider unnecessary.
