Namhyung Kim 8d73259ef2 perf ftrace latency: Remove unnecessary "--" from --use-nsec option 
The option name should not have the dashes.  Current version shows four
dashes for the option.

  $ perf ftrace latency -h

   Usage: perf ftrace [<options>] [<command>]
      or: perf ftrace [<options>] -- [<command>] [<options>]
      or: perf ftrace {trace|latency} [<options>] [<command>]
      or: perf ftrace {trace|latency} [<options>] -- [<command>] [<options>]

      -b, --use-bpf         Use BPF to measure function latency
      -n, ----use-nsec      Use nano-second histogram
      -T, --trace-funcs <func>
                            Show latency of given function

Fixes: 84005bb614 ("perf ftrace latency: Add -n/--use-nsec option")
