drm/amd/display: Check all enabled planes in dm_check_crtc_cursor

Browse source

It was only checking planes which had any state changes in the same
commit. However, it also needs to check other enabled planes.

Not doing this meant that a commit might spuriously "succeed", resulting
in the cursor plane displaying with incorrect scaling. See
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3177#note_1824263
for an example.
