drm/i915: Remove redundant trailing request flush

Browse source

Now that we perform the request flushing inline with emitting the
breadcrumb, we can remove the now redundant manual flush. And we can
also remove the infrastructure that remained only for its purpose.

v2: emit_breadcrumb_sz is in dwords, but rq->reserved_space is in bytes
