drm/nouveau: Constify struct nouveau_job_ops

Browse source

"struct nouveau_job_ops" is not modified in these drivers.

Constifying this structure moves some data to a read-only section, so
increase overall security.

In order to do it, "struct nouveau_job" and "struct nouveau_job_args" also
need to be adjusted to this new const qualifier.

On a x86_64, with allmodconfig:
Before:
