Umount not working for entries without mount options

[lexxman123]

Describe the bug
Umount is not working when mounted directory has no mount options

To Reproduce
Steps to reproduce the behavior:

Directory is mounted without mount options, e.g. :

# mount
  node       mounted        mounted over    vfs       date        options
-------- ---------------  ---------------  ------ ------------ ---------------
         /dev/hd4         /                jfs2   Nov 25 15:18 rw,log=/dev/hd8
         /dev/hd2         /usr             jfs2   Nov 25 15:18 rw,log=/dev/hd8
...
...
nim1     /export/expfs    /mnt2            nfs3   Dec 13 14:31 

ibm.power_aix.mount:
          state: umount
          mount_over_dir: "/mnt2"

Looking at plugins/modules/mount.py it says in is_fspath_mounted:

        for ln in stdout.splitlines()[1:]:
            fdirs.append(ln.split()[-6])

This fails as without mount options the correct parameter would be -5.

Expected behavior
Umount should work, even when no mount options are present
