leds: leds-ns2: set devm_gpio_request_one() flags param correctly

The devm_gpio_request_one() flags parameter was set to:

  GPIOF_DIR_OUT | gpio_get_value(template->cmd)

GPIOF_DIR_OUT and GPIOF_DIR_IN are defined as below:

  GPIOF_DIR_OUT   (0 << 0)
  GPIOF_DIR_IN    (1 << 0)

So, when 'gpio_get_value(template->cmd)' is 1, the gpio pin can
be set as input, instead of output.

To prevent this problem, GPIOF_OUT_INIT flags should be used when
using devm_gpio_request_one().

Same goes for 'gpio_get_value(template->slow)' case.
