hdd_replacement not working if autofs is used

[markuschen]

This is a mount point created by NetworkBrowser in /etc/enigma2/automounts.xml:

<autofs>
 <nfs>
  <mount>
   <active>True</active>
   <hdd_replacement>True</hdd_replacement>
   <ip>192.168.178.2</ip>
   <sharename>record</sharename>
   <sharedir>record</sharedir>
   <options>rw,nolock,tcp,rsize=32768,wsize=32768</options>
  </mount>
 </nfs>
</autofs>

The important thing here is hdd_replacement = true, so the mounted directory '/media/autofs/record' should replace the internal hdd path '/media/hdd'.
Directory '/media/hdd' is created before AutoMount.py starts and with this configuration the replacement of '/media/hdd' is not working.

Fix in pull #338

This is only a partial fix, because folders 'movie' and 'timeshift' are missing. These folders were created before AutoMount.py is running. A recording fails with 'write error, hdd full?'

Also, if only the gui is restarted (or init 4 + 3) the 'mount --bind' is running more than once. A 'umount' before could be the clou.
