RH-Commit: [24/67] 2c9e41e9ca0b67ebf807d1643a98866a0cb75768 (eauger1/centos-qemu-kvm)
Currently iommufd doesn't support dirty page sync yet,
but it will not block us doing live migration if VFIO
migration is force enabled.
So in this case we allow set_dirty_page_tracking to be NULL.
Note we don't need same change for query_dirty_bitmap because
when dirty page sync isn't supported, query_dirty_bitmap will
never be called.
