dm_plane_helper_prepare_fb with AMDGPU_GEM_DOMAIN_GTT

The error is not reproducible anymore using the latest amd-staging-4.11 branch
and the master HEAD of xf86-video-amdgpu using AMDGPU_GEM_DOMAIN_GTT in
dm_plane_helper_prepare_fb, but I still have the weird corruption with a white
background screen and a corrupted square as pointer as in the previous
attachment. In the attachment the journal when attaching and detaching the HDMI
cable.

The only concerning errors I can see in there are:

[drm:construct [amdgpu]] *ERROR* construct: Invalid Connector ObjectID from
Adapter Service for connector index:2!                                    
[drm:hwss_wait_for_blank_complete [amdgpu]] *ERROR* DC: failed to blank crtc!   
[drm:dc_create [amdgpu]] *ERROR* DC: Number of connectors is zero!
