[PATCH v2 00/20] VFIO: misc cleanups part2

[Zhenzhong Duan <zhenzhong.duan@intel.com>]

Hi

This is the last round of cleanup series to change functions in hw/vfio/
to return bool when the error is passed through errp parameter.

The first round is at 
https://lists.gnu.org/archive/html/qemu-devel/2024-05/msg01147.html

I see Cédric is also working on some migration stuff cleanup,
so didn't touch migration.c, but all other files in hw/vfio/ are cleanup now.

Patch1 and patch20 are fix patch, all others are cleanup patches.

Test done on x86 platform:
vfio device hotplug/unplug with different backend
reboot

This series is rebased to https://github.com/legoater/qemu/tree/vfio-next

Thanks
Zhenzhong
