perf report: Use parse_options_usage() for -s option failure
perf report: Use parse_options_usage() for -s option failure

The -s (--sort) option was processed after normal option parsing so that
it cannot call the parse_options_usage() automatically.  Currently it
calls usage_with_options() which shows entire help messages for event
option.  Fix it by showing just -s options.

  $ perf report -s help
    Error: Unknown --sort key: `help'

   usage: perf report [<options>]

      -s, --sort <key[,key2...]>
                            sort by key(s): pid, comm, dso, symbol, ...
