Kuniyuki Iwashima 603fc57ab7 af_unix: Skip SCM_PIDFD if scm->pid is NULL. 
syzkaller hit a WARN_ON_ONCE(!scm->pid) in scm_pidfd_recv().

In unix_stream_read_generic(), if there is no skb in the queue, we could
bail out the do-while loop without calling scm_set_cred():

  1. No skb in the queue
  2. sk is non-blocking
       or
     shutdown(sk, RCV_SHUTDOWN) is called concurrently
       or
     peer calls close()

If the socket is configured with SO_PASSPIDFD, scm_pidfd_recv() would
populate cmsg with garbage emitting the warning.

Let's skip SCM_PIDFD if scm->pid is NULL in scm_pidfd_recv().

Note another way would be skip calling scm_recv() in such cases, but this
caused a regression resulting in commit 9d797ee2dc ("Revert "af_unix:
Call scm_recv() only after scm_set_cred()."").
