Bug report

With a network drive mounted with CIFS and using the mfsymlinks options, os.path.islink and os.path.isdir will return True for a symbolic link to a directory, whereas the corresponding DirEntry for the symlink will return False for both DirEntry.is_symlink() and DirEntry.is_dir().

Repro steps:

1. Mount a CIFS drive with -o mfsymlinks to /mnt/scratch
2. mkdir /mnt/scratch/dir
3. ln -s /mnt/scratch/dir /mnt/scratch/link
4. In python 3, run os.scandir('/mnt/scratch') and iterate to the link entry
5. Validate is_symlink() and is_dir() return False
6. Run os.path.islink('/mnt/scratch/link') and os.path.isdir('/mnt/scratch/link') and validate both return True
