    gca: Return original lang_id if no remap is found
    
    If remap_langauge fails to remap, it doesn't mean there isn't a
    valid language id. So don't return NULL, but return the original lang_id
    instead for further processing. This fixes an issue with other languages
    than the remappable ones not being considered for diagnostics.
