Minor fixes and cleanups, followed by an optimization for virtio-mem

virtio-mem logically plugs/unplugs memory within a sparse memory region

plugged (populated) or unplugged (discarded).
Currently, guest_phys_blocks_append() appends the whole (sparse)
virtio-mem managed region and therefore tpm code might zero the hole
region and dump code will dump the whole region. Let's only add logically
plugged (populated) parts of that region, skipping over logically
unplugged (discarded) parts by reusing the RamDiscardMgr infrastructure
introduced to handle virtio-mem + VFIO properly.
Queued, thanks.
Thanks Paolo!
