Fix RGBMatrix set to off due to initial read

CoffeeIsLife/OpenRGB:qmk_xap_refactor into qmk_xap_refactor

This fixes a bug wherein during startup, if you had lighting soft-disabled on your keyboard (Using RGB_MATRIX_TOGGLE or a key that has that function), OpenRGB would read that during scanning and save that information to it's internal rgb_config struct. It would then never change the .enabled member resulting in .enabled = false being written to the keyboard every time the user tries to change the lighting mode.

To reproduce the bug this fixes: disable the lighting on your QMK keyboard, start OpenRGB, re-enable the lighting on your keyboard, Set the mode in OpenRGB
