leds: leds-lp3944: properly handle lp3944_configure fail in lp3944_probe

Browse source 
In current implementation, lp3944_probe return 0 even if lp3944_configure fail.
Therefore, led_classdev_unregister will be executed twice
( in error handling of lp3944_configure and lp3944_remove ).
This patch properly handles lp3944_configure fail in lp3944_probe.
