Fix bug that when accepting a socket connection and ERROR_NETNAME_DELETED occurs, leads this into a closing of the serving socket

This is done with the patches described by fercod in the GitHub thread #93821.
These patches were successfully tested by me and worked properly.
The error propagates properly without closing the original socket and without causing the server to hang.
