[CIFS] Add nodfs mount option
Older samba server (eg. 3.0.24 from Debian etch) don't work correctly,
if DFS paths are used. Such server claim that they support DFS, but fail
to process some requests with DFS paths. Starting with Linux 2.6.26,
the cifs clients starts sending DFS paths in such situations, rendering
it unuseable with older samba servers.
The nodfs mount options forces a share to be used with non DFS paths,
even if the server claims, that it supports it.
