Cannot compile on Linux 4.14.0 with VoxelBlockGridImpl.h

### Checklist

- [X] I have searched for [similar issues](https://github.com/isl-org/Open3D/issues).
- [X] For Python issues, I have tested with the [latest development wheel](https://www.open3d.org/docs/latest/getting_started.html#development-version-pip).
- [X] I have checked the [release documentation](https://www.open3d.org/docs/release/) and the [latest documentation](https://www.open3d.org/docs/latest/) (for `main` branch).

### Steps to reproduce the issue

#### I first cloned Open3D by:
```
git clone https://github.com/isl-org/Open3D.git
cd Open3D
```
Linux 4.14.0_1-0-0-44 #1 SMP Tue Sep 14 17:12:22 CST 2021 x86_64 x86_64 x86_64 GNU/Linux
#### Then, I build Open3D (on Ubuntu 20.04, with CUDA 11.5) with:

```
mkdir build
cd build
cmake ..
make -j$(nproc)
```
