drm/amdgpu: Iterate through DRM connectors correctly

Browse Source 
Currently, every single piece of code in amdgpu that loops through
connectors does it incorrectly and doesn't use the proper list iteration
helpers, drm_connector_list_iter_begin() and
drm_connector_list_iter_end(). Yeesh.

So, do that.
