[PATCH 1/3] drm/i915: Remove dead code from intel_release_load_detect_pipe()

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

As we now never attempt to steal a crtc for load detection, we either
set a mode on a new pipe, or change the dpms mode on an existing pipe.
Never both, so we can simplify the code slightly.
