ext4: disable synchronous transaction batching if max_batch_time==0
commit 5dd214248f94d430d70e9230bda72f2654ac88a8 upstream.
The mount manpage says of the max_batch_time option,
This optimization can be turned off entirely
by setting max_batch_time to 0.
But the code doesn't do that. So fix the code to do
that.
