("[PATCH v3 0/7] Do not unparent in instance_finalize()")

This patch series was spun off from "[PATCH v2 00/15] Fix memory region
leaks and use-after-finalization":
https://lore.kernel.org/qemu-devel/20250915-use-v2-0-f4c7ff13bfe9@rsg.ci.i.u-tokyo.ac.jp/

When developing the next version of "[PATCH 00/16] memory: Stop
piggybacking on memory region owners*", I faced multiple memory region
leaks and use-after-finalization. This series extracts their fixes so
that the number of Cc: won't explode.

Patch "qdev: Automatically delete memory subregions" and the succeeding
patches are for refactoring, but patch "vfio-user: Do not delete the
subregion" does fix use-after-finalization.
