    puffs - check whether the FS has the given op
    
     * Previously calls to some of the vnops that are unimplemented in the
       actual puffs filesystem were succeeding.
    
     * We now check whether the op exists before trying to pass it to
       the userland FS. If it doesn't exist, fail (or return ok if no real
       action needs to be taken).
