MDEV-32008 auto_increment value on table increments by one after restart

Browse Source 
- This issue caused by commit 4700f2ac70f8c79f2ac1968b6b59d18716f492bf(MDEV-30796)
During bulk insert operation, InnoDB wrongly stores the next autoincrement
value as current autoincrement value. So update the current autoincrement
value rather than next auto increment value.
