SmbFile.getDfsPath() returns incorrect server before connecting

[jblesener]

If you call getDfsPath() on a SmbFile object before calling any method that accesses the file, like exists(), you will get an incorrect result. If you call getDfsPath() after accessing the file, you will get the correct result.

Only tested on files accessed through a domain DFS namespace, not server DFS namespace.

This code will replicate the issue:
String filePath = "smb://domain.name/dfspath1/dfspath2";

SmbFile dfsFile = new SmbFile(filePath);

System.out.println("Initial Path: " + filePath); //prints smb://domain.name/dfspath1/dfspath2
System.out.println("DFS Path: " + dfsFile.getDfsPath()); //prints smb://dfsnameserver/dfspath1/dfspath2, only the server name changes and it is technically still a valid path but not what the function should return
System.out.println("Exists: " + dfsFile.exists());
System.out.println("DFS Path, try 2: " + dfsFile.getDfsPath()); //prints smb://fileserver/share/path
