drm/xe: Do not dereference NULL job->fence in trace points
job->fence is not assigned until xe_sched_job_arm(), check for
job->fence in xe_sched_job_seqno() so any usage of this function (trace
points) do not result in NULL ptr dereference. Also check job->fence
before assigning error in job trace points.
Fixes: 0ac7a2c745e8 ("drm/xe: Don't initialize fences at xe_sched_job_create()")
