[PATCH] selftests/futex: Correct pthread_create return value check

[Lei Zhu]

From: Lei Zhu <zhulei@xxxxxxxxxx>

The pthread_create() functions returns 0 on success and a positive value on
failure. Modify the return value check to correctly detect failure cases.

Fixes: 14d016bd7282 ("selftests/futex: Refactor futex_wait_private_mapped_file with kselftest_harness.h")
