    pioctl: limit fruitless token searches
    
    getNthCell searches the afs_users table for the nth token set belonging to a
    given user.  However, it is impossible for a user to have more than one
    token set per cell.  If the caller specifies a number greater than the
    total number of cells this cache manager knows about, we know the search
    will be fruitless.
    
    Instead, return early in this case, avoiding both the lock and the
    search.
