drm/i915: Drop checks for max_pixclk failures in cdclk computation 

commit 565602d750 ("drm/i915: Do not acquire crtc state to check clock during modeset, v4.")
removed the possibility that intel_mode_max_pixclk() or
ilk_max_pixel_rate() might return an error, so let's get rid of the
error checks in the callers as well.
