Close socket in case of errors in setting non-blocking

Browse Source 
If configuring the newly created socket non-blocking fails we
error out and return INVALID_SOCKET, but the socket that had
been created wasn't closed. Fix by issuing closesocket in the
errorpath.

Backpatch to all supported branches.
