drm/i915: Drop the nop intel_update_watermarks() call from haswell_crtc_enable()

Browse Source 
HSW+ all use the .initial_watermarks() hook, so there's no point in
calling intel_update_watermarks() from HSW+ specific code. We'll still
hang on to the .initial_watermarks NULL check since theoretically if the
memory latencies are not populated we would not populate the function
pointer either.
