drm/scheduler: remove timeout work_struct from drm_sched_job (v3)
having a delayed work item per job is redundant as we only need one
per scheduler to track the time out the currently executing job.
v2: the first element of the ring mirror list is the currently
executing job so we don't need a additional variable for it
v3: squash in fixes for v3d and etnaviv
