[PATCH] cifs: ignore the noauto option if it is provided

[Steve French]

I didn't see anything logged in dmesg (when I tried it on 5.11-rc today)
indicating it was a problem (it still tried the mount).Maybe it is stripped
out by user space?

In any case can't hurt to to ignore noauto exlpicitly as we do in 5.10 and
earlier
