    tools: gtracestat: Drop unused functions do_cstate and single_cstate helper
    
    These have always been dead code since the code was added AFAICT.
    
    This eliminates the code containing CID 10567079, 10567080, 10567081
    and 10567082 (all apparently some confusion between max_cx_num vs
    MAX_CX_NR, but given the lack of callers its hard to tell what was
    intended)
