onboard_hub_power_off() currently has a delay after asserting the
reset of the hub. There is already a delay in onboard_hub_power_on()
before de-asserting the reset, which ensures that the reset is
asserted for the required time, so the delay in _power_off() is not
needed.
Skip the reset GPIO check before calling gpiod_set_value_cansleep(),
the function returns early when the GPIO descriptor is NULL.
