This test case checks for failure of the cloned device mounts, which
is no longer true after the commit a5b8a5f9f835 ("btrfs: support
cloned-device mount capability"). So check for the non-presence the
temp-fsid feature and do not test for the failure of the cloned device
mount.

v3: check only that mount of clone device fails if temp-fsid is not
supported.
