Subject: [PATCH] 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)
