ServiceHostBase-Patch to correct wrong check

A wrong null-check in ServiceHostBase.OnEndClose() function causes the following exception:

Object reference not set to an instance of an object
System.ServiceModel

  at System.ServiceModel.ServiceHostBase.OnBeginClose (TimeSpan timeout, System.AsyncCallback callback, System.Object state) [0x00000] in <filename unknown>:0 
  at System.ServiceModel.Channels.CommunicationObject.BeginClose (TimeSpan timeout, System.AsyncCallback callback, System.Object state) [0x00000] in <filename unknown>:0 
  at XX.WCFService+WCFServer.Stop () [0x00000] in <filename unknown>:0 

The wrong check "if (close_delegate != null)" should be "if (close_delegate == null)", to check if the delegate was created.
