drm/dp: don't mark the AUX backlight enabled when enabling failed
If drm_edp_backlight_enable() fails, dp_aux_backlight_update_status()
still marks the backlight as enabled. From then on every brightness
change only updates the level and the enable is never retried, so the
panel stays dark until something blanks and unblanks the backlight.
Return the error instead, so the next update tries to enable again.
Fixes: 10f7b40e4f30 ("drm/panel: add basic DP AUX backlight support")
