[WHY]
commit c6417b87e7c3 ("drm/amd/display: Set native cursor mode for
disabled CRTCs again") made amdgpu_dm_crtc_get_cursor_mode() report
native mode for a disabled CRTC, by adding !dm_crtc_state->base.enable
to the DCN4x IP version check that returned early.
commit b7d7e714de44 ("drm/amd/display: Fall back to overlay cursor on
dcn4x when top plane doesn't fill CRTC") then replaced that early
return with a skip_fmt_scale_restrictions flag, so dcn4x falls through
to the coverage check instead. The disabled CRTC condition shared the
same if statement and lost its early return as well. A disabled CRTC
now reaches the coverage check and is given overlay mode whenever the
top plane does not fill the CRTC, which can make an atomic commit that
disables the CRTC fail.
[HOW]
Move the disabled CRTC check into its own early return ahead of the DCN4x
IP version check, so it reports native mode on every ASIC.
