leds: trigger: netdev: uninitialized variable in netdev_trig_activate()

Browse source 
The qca8k_cled_hw_control_get() function which implements ->hw_control_get
sets the appropriate bits but does not clear them.  This leads to an
uninitialized variable bug.  Fix this by setting mode to zero at the
start.
