drm/i915: Don't return busy for buffers left on the flushing list.
These buffers don't have active rendering still occurring to them, they just
need either a flush to be emitted or a retire_requests to occur so that we
notice they're done. Return unbusy so that one of the two occurs. The two
expected consumers of this interface (OpenGL and libdrm_intel BO cache) both
want this behavior.
