Refer to the original commit: 27a65a4

For empty `out_backprop` inputs (e.g. `[3, 1, 0, 1]`), the current
CPU/GPU kernels fail (one with dnnl, the other with cudnn). Added
a shortcut path to return a zero input.

Note that the XLA test currently fails due to an incorrect result
size bug (b/239598470), so it is currently disabled.
