Revert "af_unix: Call scm_recv() only after scm_set_cred()."
This reverts commit 3f5f118bb657f94641ea383c7c1b8c09a5d46ea2.
Konrad reported that desktop environment below cannot be reached after
commit 3f5f118bb657 ("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().
