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

[ivlipski]

From: Ivan Lipski <ivlipski@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.

[PATCH 2/2] Revert "drm/amd/display: Add NULL check for 'afb' before dereferencing in amdgpu_dm_plane_handle_cursor_update"

[ivlipski]

From: Ivan Lipski <ivlipski@amd.com>

[WHY]
This patch is a dupplicate implementation of 14bcf29b, which we
are reverting due to a regression with kms_plane_cursor IGT tests.

This reverts commit 0d84450ae0db367780c3dd2e208fe4e6fe5565b8.
