f2fs: change default schedule timeout value
This patch changes default schedule timeout value from 20ms to 1ms,
in order to give caller more chances to check whether IO or non-IO
congestion condition has already been mitigable.
In addition, default interval of periodical discard submission is
kept to 20ms.
