Fix broken macro guard in rgb_led_off()

[okdana]

I noticed that the #endif for the ENABLE_MODE_LED_RGB guard inside rgb_led_off() is placed inside save_mode(), so if that macro is actually undefined it won't compile. I think this is what you were going for?

Also, a semi-related but minor nit-pick: I found the placement of these functions in the file a little weird. Would it make sense to change the order from this...

void rgb_led_off() { ... }
inline void save_mode () { ... }
inline void change_mode (int increment) { ... }
inline void next_mode () { ... }
void rgb_led_update () { ... }
void flash_single_led () { ... }
void set_mode (VideoMode m, boolean save) { ... }

... to something like this (so that related ones are grouped together)?

inline void save_mode () { ... }
inline void change_mode (int increment) { ... }
inline void next_mode () { ... }
void set_mode (VideoMode m, boolean save) { ... }
void rgb_led_off() { ... }
void rgb_led_update () { ... }
void flash_single_led () { ... }

I can submit another PR if you like that.

You are right! Can you please resubmit this against the experimental branch?

About the order of functions, I'll fix that myself ASAP, thanks.

Thanks, updated the PR to apply to experimental
