[PATCH 1/2] tools: gtracestat: Drop unused functions do_cstate and single_cstate helper

[Ian Campbell <ian.campbell@citrix.com>]

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)
