for proper refcounting to take place as we use
i915_add_request() for it.
i915_add_request() also takes the context for the request
from ring->last_context so move the null state batch
submission after the ring context has been set.
v2: we need to check for correct ring now (Ville Syrjälä)
v3: no need to expose i915_gem_move_object_to_active (Chris Wilson)
v4: cargoculted vma/active/inactive error handling removed (Chris Wilson)

HW guys say that it is not a cool idea to let device
go into rc6 without proper 3d pipeline state.
For each new uninitialized context, generate a
valid null render state to be run on context
creation.
This patch introduces a skeleton with empty states.
v2: - No need to vmap (Chris Wilson)
- use .c files for state (Daniel Vetter)
- no need to flush as i915_add_request does it
- remove parameter for batch alloc size
- don't wait for the init (Ben Widawsky)
v3: - move to cpu/gpu (Chris Wilson)
