A build error when DRM_NOUVEAU_BACKLIGHT is not defined
disp.c:1665:52: error: 'struct nouveau_connector' has no
  member named 'backlight'

Use ifdef's similar to elsewhere in disp.c to conditionally
use the new backlight support.

Move scope of drm to where it is used, inside the backlight error
reporting.

Remove shadow ret decl.

Fixes: 6eca310e8924 ("drm/nouveau/kms/nv50-: Add basic DPCD backlight support for nouveau")
