[PATCH] drm/v3d: Move drm_sched_job_init to v3d_job_init

[Daniel Vetter <daniel.vetter@ffwll.ch>]

Prep work for using the scheduler dependency handling. We need to call
drm_sched_job_init earlier so we can use the new drm_sched_job_await*
functions for dependency handling here.

v2: Slightly better commit message and rebase to include the
drm_sched_job_arm() call (Emma).
