[PATCH] drm/scheduler: remove full_recover from drm_sched_start

This was basically just another one of amdgpus hacks. The parameter
allowed to restart the scheduler without turning fence signaling on
again.
That this is absolutely not a good idea should be obvious by now since
the fences will then just sit there and never signal.
While at it cleanup the code a bit.
