cifs: improve checking of DFS links over STATUS_OBJECT_NAME_INVALID
Do not map STATUS_OBJECT_NAME_INVALID to -EREMOTE under non-DFS
shares, or 'nodfs' mounts or CONFIG_CIFS_DFS_UPCALL=n builds.
Otherwise, in the slow path, get a referral to figure out whether it
is an actual DFS link.
This could be simply reproduced under a non-DFS share by running the
following
$ mount.cifs //srv/share /mnt -o ...
$ cat /mnt/$(printf '\U110000')
cat: '/mnt/'$'\364\220\200\200': Object is remote
Fixes: c877ce47e137 ("cifs: reduce roundtrips on create/qinfo requests")
