You'll need to set your own in your copy/revision of the code, to match
the GPU. The value will be in the thousands or even millions.
Alternatively, you could keep DES_BS_DEPTH small - maybe even as small
as 32 - and reuse the approach and maybe even code that we use to
support multiple threads on CPU to support multiple OpenCL work-items.
The latter may allow a binary build of John to adapt to different GPUs.

This is the case for builds with 128-bit SIMD vectors on CPU. Other
builds use other values of DES_BS_DEPTH.
