[PATCH hci-dev v3 0/2] vfio/migration: don't touch the device on guest shutdown #VSTOR-153976

[Andrey Drobyshev <andrey.drobyshev@virtuozzo.com>]

v2 -> v3:

 - new patch 1: stop the device when QEMU quits or migrates a VM that
   a guest shutdown left stopped. A VF closed while running, after the
   Linux guest driver unloaded, breaks the next VM that resumes on it;
 - the stop at the start of a save moved to patch 1 and now covers only
   the SHUTDOWN run state, so a suspended guest is left alone (Sashiko);
 - the guest shutdown check is one helper, used by both VM state
   handlers.

v2: http://lore.virtuozzo.com/qemu/20261108205050.37277-1-andrey.drobyshev@virtuozzo.com/
