Sometimes drivers need to be able to submit multiple jobs which depend on
each other to different schedulers at the same time, but using
drm_sched_job_add_dependency() can't fail any more after the first job is
initialized.
This function preallocate memory for dependency slots so that no ENOMEM

The problem is that drivers sometimes need to add dependencies without

Add a function which preallocates slots by inserting signaled stub fences
into the dependency array.

allocating any memory.
Add a function which preallocates slots by inserting signaled stub fences
into the dependency array.
