Don't derive comparison traits for cudaHostNameParams.*.

In `cust_raw`, we derive `PartialEq`/`Eq`/`PartialOrd`/`Ord` for all
types by default. However, `cudaHostNodeParams` and
`cudaHostNodeParamsV2` each contain a raw pointer, which causes this
warning:
```
function pointer comparisons do not produce meaningful results since
their addresses are not guaranteed to be unique
```

bindgen has a `no_partialeq` function that disables all of these derives
for relevant types. Only `PartialOrd`/`Ord` cause a problem, but there
is no easy way to disable those while keeping `PartialEq`/`Eq`, so this
will have to do. We already use `no_partialeq` for
`CUDA_HOST_NODE_PARAMS.*` and various other types.
