[PATCH] leds: leds-cobalt-qube: Use devm_led_classdev_register

[Vaishali Thakkar]

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 and unneeded label is dropped. Also, remove redundant
cobalt_qube_led_remove.
