smb: client: fix broken file attrs with nodfs mounts
*_get_inode_info() functions expect -EREMOTE when query path info
calls find a DFS link, regardless whether !CONFIG_CIFS_DFS_UPCALL or
'nodfs' mount option. Otherwise, those files will miss the fake DFS
file attributes.
Before patch
$ mount.cifs //srv/dfs /mnt/1 -o ...,nodfs
$ ls -l /mnt/1
ls: cannot access '/mnt/1/link': Operation not supported

After patch
