    libctf: fix dict leak on archive-wide symbol lookup error path
    
    If a lookup fails for a reason unrelated to a lack of type data for this
    symbol, we return with an error; but we fail to close the dict we opened
    most recently, which is leaked.
    
    libctf/
            * ctf-archive.c (ctf_arc_lookup_sym_or_name): Close dict.
