    dom0less: Fix LLC coloring when mixing colored and non-colored domains
    
    llc_colors_str being outside the main loop makes domains without
    explicit coloring inherit the colors of the last colored domain parsed.
    
    Move it inside so that's no longer the case.
    
    Fixes: 5948dc16759c("xen/arm: add support for cache coloring...")
