resolv: Always set *resplen2 out parameter in send_vc [BZ #19825]
In various error scenarios (for example, if the server closes the TCP connection before sending the full response), send_vc can return without resetting the *resplen2 value. This can pass uninitialized or unexpected data to the caller.
