[LTP] [PATCH 3/3] pounder/cpufreq: Skip the test if processors are not supported by cpufreq

[Li Wang <liwang@redhat.com>]

During the pounder21/cpufreq test, it print so many errors:

[2015-08-17 08:43:24] (17818) cpufreq.bin: FAIL with code 4.
[2015-08-17 08:43:24] (17818) cpufreq.bin: START loop #2.
[2015-08-17 08:43:25] (17812) cpufreq.bin: FAIL with code 4.
[2015-08-17 08:43:25] (17812) cpufreq.bin: START loop #2.
[2015-08-17 08:43:27] (17812) cpufreq.bin: FAIL with code 4.
...

The reason is that the case canceled some cpufreq check steps before,
now reuse them to make sure it could be skiped on a system without
cpufreq support.
