But, to implement the CPU job with user extensions, we want v3d_get_extensions() to be able to parse CPU job data and assign it to the `struct v3d_cpu_job`. Therefore, allow the function v3d_get_extensions() to use `struct v3d_cpu_job *` as a parameter. If the `struct v3d_cpu_job *` is assigned to NULL, it means that the job is a GPU job and CPU job extensions should be rejected.
