drm/amd/display: Fix 'panel_cntl' could be null in 'dcn21_set_backlight_level()'
'panel_cntl' structure used to control the display panel could be null,
dereferencing it could lead to a null pointer access.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn21/dcn21_hwseq.c:269 dcn21_set_backlight_level() error: we previously assumed 'panel_cntl' could be null (see line 250)
Fixes: 474ac4a875ca ("drm/amd/display: Implement some asic specific abm call backs.")
