Cleanup missing for tcp socket connections re-opened on close event

[lvjkumar]

Connections re-opened on the close event of the socket do not get cleaned up anywhere.

winston-syslog.js
`.on('close', () => {
//
// Attempt to reconnect on lost connection(s), progressively
// increasing the amount of time between each try.
//
const interval = Math.pow(2, this.retries);
this.connected = false;

    setTimeout(() => {
      this.retries++;
      **this.socket.connect(this.port, this.host);**
    }, interval * 1000);
  })`
