The GPU Scheduler now supports a new callback, cancel_job(), which lets
the scheduler cancel all jobs which might not yet be freed when
drm_sched_fini() runs. Using this callback allows for significantly
simplifying the mock scheduler teardown code.
Implement the cancel_job() callback and adjust the code where necessary.

There is no need for separate locks for single jobs and the entire
scheduler. The dma_fence context can be protected by the scheduler lock,
allowing for removing the jobs' locks. This simplifies things and
reduces the likelyhood of deadlocks etc.
Replace the jobs' locks with the mock scheduler lock.
