drm/rockchip: vop: Don't crash for invalid duplicate_state()
[ Upstream commit 1449110b0dade8b638d2c17ab7c5b0ff696bfccb ]
It's possible for users to try to duplicate the CRTC state even when the
state doesn't exist. drm_atomic_helper_crtc_duplicate_state() (and other
users of __drm_atomic_helper_crtc_duplicate_state()) already guard this
with a WARN_ON() instead of crashing, so let's do that here too.
Fixes: 4e257d9eee23 ("drm/rockchip: get rid of rockchip_drm_crtc_mode_config")
