I compared this method with AdoptConnectedSocket. The difference about
|peer_address| is expected, but I don't understand why this method doesn't need
to create |core_|. Could you add a comment to explain that?

|core_| is only used for read/write operations and not used when the socket only
does accept. Comments to make it less surprising.
