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.
