drm/amdgpu: update drm_display_info correctly when the edid is read
drm_display_info is updated by drm_get_edid() or
drm_connector_update_edid_property(). In the amdgpu driver it is almost
always updated when the edid is read in amdgpu_connector_get_edid(),
but not always. Change amdgpu_connector_get_edid() and
amdgpu_connector_free_edid() to keep drm_display_info updated.
