Increase step between checks for cancellation (elastic#53712)

The introduction of the ExitableDirectoryReader showed increase of
latencies for range queries using pointvalues.

Check for cancellation every 1024 docs instead of every 15 to lower
the impact of the check in query's performance.

Follows: elastic#52822
Fixes: elastic#53496
