Re: [PATCH net] selftests: af_unix: verify SCM_PIDFD pidfd in cmsg_check_dead()

The cmsg_check_dead() function receives an expected_pid parameter but never
actually verifies that the pidfd received via SCM_PIDFD corresponds to that
PID. It only checks the child's exit code via PIDFD_GET_INFO.

this breaks the test:

  (scm_pidfd.c:282: errno: None) wrong SCM_PIDFD -1 != <PID>

If you want to improve the test please repost this patch in 2 weeks
after the merge window. This patch should not carry the Fixes tag.
