[PATCH] drm/amdgpu: Fix connector atomic_check compilation fail

[Sean Paul]

From: Sean Paul <seanpaul at chromium.org>

I missed amdgpu in my connnector_helper_funcs->atomic_check conversion,
which is understandably causing compilation failures.

Fixes: 6f3b62781bbd ("drm: Convert connector_helper_funcs->atomic_check to accept drm_atomic_state")
