Remove the "exists" parameter from create_msdfs_link
Jeremy, setting "exists" to True in _dfs_Add prevented the initial creation of a new symlink for me, because the SMB_VFS_UNLINK failed. This also exists in 3.2. I only check it into 3.3 as I would like you to look at it first. Thanks, Volker (This used to be commit f58b098a4172949018e84c4d0c722d6eb9bba514)
