pthread/tst-cancel28: Fix barrier re-init race condition
When running this test on the OpenRISC port I am working on this test fails with a timeout. The test passes when being straced or debugged. Looking at the code there seems to be a race condition in that: 1 main thread: calls xpthread_cancel 2 sub thread : receives cancel signal 3 sub thread : cleanup routine waits on barrier 4 main thread: re-inits barrier 5 main thread: waits on barrier After getting to 5 the main thread and sub thread wait forever as the 2 barriers are no longer the same. Removing the barrier re-init seems to fix this issue. Also, the barrier does not need to be reinitialized as that is done by default. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
