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.

Subject: [PATCH V2] 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.
