fix: saptune should not fail on NA parameters.

[SteffenBoThomsen]

Problem

When running saptune solution verify, an error is thrown, when some parameters are misconfigured from saptunes perspective, even though they do not apply to the type of system, e.g;

   2684254, 23      | governor                           | all:performance             |           | all:powersave               | no
   2684254, 23      | grub:intel_idle.max_cstate         | 1                           |           | NA                          | no  [2] [3] [6]
   2684254, 23      | grub:numa_balancing                | disable                     |           | NA                          | no  [2] [3] [6]
   2684254, 23      | grub:processor.max_cstate          | 1                           |           | NA                          | no  [2] [3] [6]
   2684254, 23      | grub:transparent_hugepage          | never                       |           | NA                          | no  [2] [3] [6]

In this example, note 2684254 also affects other parameters, like:

   2684254, 23      | KSM                                | 0                           |           | 0                           | yes
   2684254, 23      | THP                                | never                       |           | never                       | yes
   2684254, 23      | energy_perf_bias                   | all:0                       |           | all:none                    |  -  [1]
   2684254, 23      | force_latency                      | 70                          |           | all:none                    |  -  [1]
   2684254, 23      | kernel.numa_balancing              | 0                           |           | 0                           | yes

Solution

Set failed_when to false, to not fail on NA parameters.
