[PATCH 2/2] leds: triggers: Don't remove trigger if LED_KEEP_TRIGGER flag is set

[Guru Das Srinagesh]

From: Fenglin Wu <fengl...@codeaurora.org>

The LED_KEEP_TRIGGER flag prevents the trigger being removed while
turning off the LEDs. Extend the flag usage to prevent the trigger being
removed even while "none" trigger is set.
