Good idea but we can do it without adding a new mount option.
Instead of "cache=ro" I think we should look at the WRITE bit in the
tree connect response access mask since this should tell us if the share is
read-only server-side or not.

If the share is thus read-only we should then have that reflected in the
"ro" mount option.

* use TreeConnect/AccessMaks/WRITE flag to enable this more aggressive caching
and not a mount option.
* Probably also fail the mount if the WRITE flag is clear and the user
did not specify "ro"
as a mount option.
