JBD: round commit timer up to avoid uncommitted transaction
Fix jiffie rounding in jbd commit timer setup code. Rounding down could cause the timer to be fired before the corresponding transaction has expired. That transaction can stay not committed forever if no new transaction is created or explicit sync/umount happens.
