Namhyung Kim cc03c54296 perf stat: Enhance option parse error message 
Print related option help messages only when it failed to process
options.  While at it, modify parse_options_usage() to skip usage part
so that it can be used for showing multiple option help messages
naturally like below:

  $ perf stat -Bx, ls
  -B option not supported with -x

   usage: perf stat [<options>] [<command>]

      -B, --big-num         print large numbers with thousands' separators
      -x, --field-separator <separator>
                            print counts with custom separator
