Daniel Bristot de Oliveira 5f0769331a rtla/timerlat: Simplify "no value" printing on top
Instead of printing three times the same output, print it only once,
reducing lines and being sure that all no values have the same length.

It also fixes an extra '\n' when running the with kernel threads, like
here:

     =============== %< ==============
                                      Timer Latency

   0 00:00:01   |          IRQ Timer Latency (us)        |         Thread Timer Latency (us)
 CPU COUNT      |      cur       min       avg       max |      cur       min       avg       max
   2 #0         |        -         -         -         - |      161       161       161       161
   3 #0         |        -         -         -         - |      161       161       161       161
   8 #1         |       54        54        54        54 |        -         -         -         -'\n'

 ---------------|----------------------------------------|---------------------------------------
 ALL #1      e0 |                 54        54        54 |                161       161       161
     =============== %< ==============

This '\n' should have been removed with the user-space support that
added another '\n' if not running with kernel threads.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
