Hi

This is a cleanup series to change VFIOIOMMUClass callbacks to return
bool when the error is passed through errp parameter.

See discussion at https://lists.gnu.org/archive/html/qemu-devel/2024-04/msg04782.html

It looks many functions in VFIO sub-system need same change,
so this can be a very first series.

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

Thanks
Zhenzhong
