We will move SOCK_PASS{CRED,PIDFD,SEC} from struct socket.flags
to struct sock for better handling with SOCK_PASSRIGHTS.
Then, we don't need to access struct socket in maybe_add_creds().
Let's pass struct sock to maybe_add_creds() and its caller
queue_oob().
While at it, we append the unix_ prefix and fix double spaces
around the pid assignment.
