[LTP] [PATCH] tst_test: Fix exit value on tst_brk(TCONF, ...)

[Cyril Hrubis]

We decided not to propagate TCONF into the test exit value in a case
that the test had at least one TPASS in:

commit 5390d6ea36578c1fac8adc416b6f91aa4a330a08

    lib/tst_test: Report 0 if test has both TPASS and TCONF

However this commit missed a case when TCONF is passed directly to the
do_exit() function. This may happen in two cases actually, one of the is
tst_brk(TCONF, ...) called from a test and second one is more subtle and
happens when the last result in the run_tcases_per_fs() produces TCONF
which is then propagated to the do_exit() function.

This commit simply mask the TCONF from the exit value in this cases if
we happen to have non-zero success counter.
