leds: Clear LED_INIT_DEFAULT_TRIGGER when clearing current trigger
Not all triggers use LED_INIT_DEFAULT_TRIGGER, which means that it
will not get cleared when the default trigger is a trigger which
does not use it such as "default-on".
If the default trigger then later gets replaced by a trigger which
does check LED_INIT_DEFAULT_TRIGGER, such as "timer" then that trigger
will behave as if it is the default trigger which it should not do.
To fix this clear the LED_INIT_DEFAULT_TRIGGER flag when clearing
the current trigger, so that it will not be set for any subsequently
set (non default) triggers.
