leds: leds-cobalt-qube: Use devm_led_classdev_register
Use resource-managed function devm_led_classdev_register instead
of led_classdev_register to make the error-path simpler.
To be compatible with the change, goto is replaced with direct
return, unneeded label err_null is dropped and unnecessary variable
retval is removed. Also, remove redundant cobalt_qube_led_remove.
