drm: Get rid of drm_sched_job.id

Browse Source 
Its only purpose was for trace events, but jobs can already be
uniquely identified using their fence.

The downside of using the fence is that it's only available
after 'drm_sched_job_arm' was called which is true for all trace
events that used job.id so they can safely switch to using it.
