regulator: gpio: check return value of of_get_named_gpio
At boot time the regulator driver can be initialized before the gpio, in which case the call to of_get_named_gpio will return EPROBE_DEFER. This value is silently passed to regulator_register which will return success, although the gpio is not registered (regulator_ena_gpio_request not called) as the value passed is detected as invalid. The gpio_regulator_probe will therefore succeed win no gpio requested.
