[PATCH 09/11] leds: trigger: netdev: init mode if hw control already active

[Christian Marangi]

On netdev trigger activation, hw control may be already active by
default. If this is the case, init the already active mode and set the
bool to hw_control bool to true to reflect the already set mode in the
trigger_data.
