Fix stopping link loops in QDirIterator on Windows
Fix stopping link loops in QDirIterator on Windows

currentFileInfo is only used for returning from the public functions
since the file info used in the algorithm is one step ahead.
nextFileInfo is the one actually used in the algorithm. The bug was
introduced in a compile fix for Windows and broke the stopLinkLoop test
for QDirIterator.
