leds: gpio: Fix uninitialized gpio label for fwnode based probe

When switching to using generic LED name composition mechanism via
devm_led_classdev_register_ext() API the part of code initializing
struct gpio_led's template name property was removed alongside.
It was however overlooked that the property was also passed to
devm_fwnode_get_gpiod_from_child() in place of "label" parameter,
which when set to NULL, results in gpio label being initialized to '?'.

It could be observed in debugfs and failed to properly identify
gpio association with LED consumer.

Fix this shortcoming by updating the GPIO label after the LED is
registered and its final name is known.
