perf report: Hide tip message when -q option is given

The tip message at the end was printed regardless of the -q option.

Originally, the message suggested only '-s comm,dso' option for higher
level view when no sort option and parent option were given.

Now it shows random help message regardless of the options so the
condition can be simplified to honor the -q option.

Committer notes:

Before:

  $ perf report --stdio -q
    42.77%  ls       ls                [.] _init
    13.21%  ls       ld-2.24.so        [.] match_symbol
    12.55%  ls       libc-2.24.so      [.] __strcoll_l
    11.94%  ls       libc-2.24.so      [.] _init

  #
  # (Tip: Show current config key-value pairs: perf config --list)
  #
  $

After:

  $ perf report --stdio -q
    42.77%  ls       ls                [.] _init
    13.21%  ls       ld-2.24.so        [.] match_symbol
    12.55%  ls       libc-2.24.so      [.] __strcoll_l
    11.94%  ls       libc-2.24.so      [.] _init

  $

We still have those two extra lines tho (that git commit insists in
turning into one, or git commit --amend doesn't make me add), food for
another patch...
