MDEV-24720 AHI removal during rollback of bulk insert

Browse Source 
InnoDB fails to remove the ahi entries during rollback
of bulk insert operation. InnoDB throws the error when
validates the ahi hash tables. InnoDB should remove
the ahi entries while freeing the segment only during
bulk index rollback operation.
