[PATCH 32/41] drm/i915: Rename ->emit_request to ->emit_breadcrumb

[Chris Wilson <chris@chris-wilson.co.uk>]

Now that the emission of the request tail and its submission to hardware
are two separate steps, engine->emit_request() is confusing.
engine->emit_request() is called to emit the breadcrumb commands for the
request into the ring, name it such (engine->emit_breadcrumb).
