Kuniyuki Iwashima 9d797ee2dc Revert "af_unix: Call scm_recv() only after scm_set_cred()."
This reverts commit 3f5f118bb6.

Konrad reported that desktop environment below cannot be reached after
commit 3f5f118bb6 ("af_unix: Call scm_recv() only after scm_set_cred().")

  - postmarketOS (Alpine Linux w/ musl 1.2.4)
  - busybox 1.36.1
  - GNOME 44.1
  - networkmanager 1.42.6
  - openrc 0.47

Regarding to the warning of SO_PASSPIDFD, I'll post another patch to
suppress it by skipping SCM_PIDFD if scm->pid == NULL in scm_pidfd_recv().
