NetworkPkg: Fix service binding issue in TCP dxe.

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.
