We used to rely upon NumRows to determine if there are
new pages available. This is not correct since the server
is allowed to return empty pages with has_more_data flag
set and the needed data to do this is not exposed by
the gocql driver.
We simply remove these checks and let the driver decide
when to stop reading.
