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
  total 0
  -rwxr-xr-x 1 root root 0 Jul 26  2022 dfstest2_file1.txt
  drwxr-xr-x 2 root root 0 Aug  8  2022 dir1
  d????????? ? ?    ?    ?            ? link

After patch

  $ mount.cifs //srv/dfs /mnt/1 -o ...,nodfs
  $ ls -l /mnt/1
  total 0
  -rwxr-xr-x 1 root root 0 Jul 26  2022 dfstest2_file1.txt
  drwxr-xr-x 2 root root 0 Aug  8  2022 dir1
  drwx--x--x 2 root root 0 Jun 26 20:29 link
