FIX - Keyboard LEDS

The main issue was I used a setup structure on the stack which turned into garbage.  Earlier I thought the data was copied, but it was not...

Found that fixing this resolved the earlier issue where I needed to defer the update.  So removed the defered code, plus use member variable for the one byte output instead of static variable.
