SYCL failures for fluids example on SunSpot

I've seen some failures on SunSpot with the fluids examples. The general behavior is:

- `/gpu/sycl/ref` passes fine everytime
- `/gpu/sycl/shared` fails about 90% of the time
- `/gpu/sycl/gen` fails about 10% of the time

The failures are only present on a few tests (SunSpot is down for maintenance today, so I can't confirm which ones exactly right now, but I'm fairly certain the Gaussian wave tests are one of them), but the above behavior is pretty consistent. This is observed using the `oneapi/release/2024.04.15.001`.

The failure specifically is a non-linear solver divergence:
```
[0]PETSC ERROR: --------------------- Error Message --------------------------------------------------------------
[0]PETSC ERROR: TSStep has failed due to DIVERGED_NONLINEAR_SOLVE, increase -ts_max_snes_failures or make negative to attempt recovery
```

Given the relationships between the backends, I'm guessing the error is probably in the shared functions between the `shared` and `gen` backends.
