    drm/amd/display: Fix BUG_ON during CRTC atomic check update

    For cases where the CRTC is inactive (DPMS off), where a modeset is not
    required, yet the CRTC is still in the atomic state, we should not
    attempt to update anything on it.

    Previously, we were relying on the modereset_required() helper to check
    the above condition. However, the function returns false immediately if
    a modeset is not required, ignoring the CRTC's enable/active state
    flags. The correct way to filter is by looking at these flags instead.

    Fixes: e277adc5a06c "drm/amd/display: Hookup color management functions"
