[PATCH 1/2] Revert "drm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor"

[ivlipski]

From: Ivan Lipski <ivlip...@amd.com>

[WHY]
This commit introduced a regression with kms_plane_cursor IGT
tests, causing AMD Asics to fail these tests.

This reverts commit 14bcf29b706f8ef423b86c9b783055b5b0c2cd35.
