perf debug: Set debug_peo_args and redirect_to_stderr variable to correct values in perf_quiet_option()

When perf uses quiet mode, perf_quiet_option() sets the 'debug_peo_args'
variable to -1, and display_attr() incorrectly determines the value of
'debug_peo_args'.  As a result, unexpected information is displayed.

Before:

  # perf record --quiet -- ls > /dev/null
  ------------------------------------------------------------
  perf_event_attr:
    size                             128
    { sample_period, sample_freq }   4000
    sample_type                      IP|TID|TIME|PERIOD
    read_format                      ID|LOST
    disabled                         1
    inherit                          1
    mmap                             1
    comm                             1
    freq                             1
    enable_on_exec                   1
    task                             1
    precise_ip                       3
    sample_id_all                    1
    exclude_guest                    1
    mmap2                            1
    comm_exec                        1
    ksymbol                          1
    bpf_event                        1
  ------------------------------------------------------------
  ...

After:
  # perf record --quiet -- ls > /dev/null
  #

redirect_to_stderr is a similar problem.

Fixes: f78eaef ("perf tools: Allow to force redirect pr_debug to stderr.")
Fixes: ccd2674 ("perf tool: Provide an option to print perf_event_open args and return value")
