v2: Handle error case in SockCreateChild and fix typo issue when we destroy the socket Sock and its associated protocol control block, we need to first close the parent protocol, then remove the protocol from childHandle and last to free any data structures that allocated in CreateChild. But currently, we free the socket data (Socket ConfigureState) before removing the protocol form the childhandle. So if the up layer perform the driverbing stop to abort tcp session and send the tcp reset packet, it will failed.
