nodfs only works when vers=1.0

[Chad W Seys <cwseys@xxxxxxxxxxxxxxxx>]

Hello,
   It looks like 'nodfs' option works when vers=1.0, but not when 
vers=2.0 (and higher I assume).
   The use case : I'm wanting to back up each samba server separately 
from the same backup server. I mount each server on a separate mount 
point, then back up each mount point.

Thanks for your work!
Chad.
