drm/amd/display: Restore guard against default backlight value < 1 nit
Mark reports that brightness is not restored after Xorg dpms screen blank.
This behavior was introduced by commit d9e865826c20 ("drm/amd/display:
Simplify brightness initialization") which dropped the cached backlight
value in display code, but also removed code for when the default value
read back was less than 1 nit.
Restore this code so that the backlight brightness is restored to the
correct default value in this circumstance.
