Description:
A value of -1 was inserted into autoinc column during ndb node shutdown. 

How to repeat:
The following situation led into this error:

-) ndb cluster (4 node, 2 replicas) running on two machines
-) insert - procedure ./ins.pl -n 100 -r 40000 -t myvalue was running on machine 1
-) shutdown nodes on the other machine using ndb_mgm> x stop
(I waited with 2 stop until the clusterlog told us that node shutdown has completed)
-) the insert procedure generated errors
