[LTP] [PATCH 1/1] cgroup_regression_test.sh: Fix TWARN usage

[Petr Vorel]

Hi Cristian,

> Using TWARN to report that a specific sub-testcase is skipped
> caused the whole cgroup_regression_test.sh to be reported as
> FAILING. Using TCONF instead.

Right, TWARN is not good (IMHO TWARN is not popular in LTP testsuites due marking test failing),
but if you don't mind I'd merge it with TBROK (more appropriate in this case).

Other option would be to use TINFO and don't skip test (we're trying to find
kernel crashes, don't we), that's probably a bit crazy.

Kind regards,
Petr
