[PATCH] cifs: ignore auto and noauto options if given

[Steve French]

Merged into cifs-2.6.git (seems harmless, and probably slightly safer
to include this - even though currently I can't reproduce the reported
problem).

Let me know if anyone else has been able to reproduce it - even with
Adam's suggested /etc/fstab line, I wasn't able to repro it.
