sem/i915: Simplify intel_cdclk_update_hw_state()

intel_crtc_calculate_min_cdclk() can't return an error
(since commit 5ac860c ("drm/i915: Fix DBUF bandwidth vs.
cdclk handling")) so there is no point in checking for one.

Also we can just call it unconditionally since it itself
checks crtc_state->hw.enabled. We are currently checking
crtc_state->hw.active in the readout path, but active==enabled
during readout, and arguably enabled is the more correct thing
to check anyway.
