Windows: Reparse Policy vs DFSLinks

When a reparse policy is specified and AFSLocateNameEntry() returns
with STATUS_REPARSE, do not re-evaluate the path with the reparse
policy disabled.  STATUS_REPARSE was returned because the FileObject's
FileName was modified and the IO Manager needs to reparse the request.
