The one of the latest change to the driver reveals the problem that
the error codes from callee aren't propagated to the caller of
__sso_led_dt_parse(). Fix this accordingly.
Fixes: 9999908ca1ab ("leds: lgm-sso: Put fwnode in any case during ->probe()")
Fixes: c3987cd2bca3 ("leds: lgm: Add LED controller driver for LGM SoC")
