[PATCH v2 0/3] virtio-balloon: free page hinting fixes

[David Hildenbrand]

Some fixes for VIRTIO_BALLOON_F_FREE_PAGE_HINT. First issue was reported by
Alexander Bulekov [1], the other ones were discovered by me when digging
into the details.

We keep finding more issues, let's see how we'll proceed with this feature
long-term. These patches can be backported to stable QEMU.
