[PATCH v1 0/2] vhost: memslot handling improvements

[David Hildenbrand <david@redhat.com>]

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.
