From: John Harrison <John.C.Harrison@xxxxxxxxx>
It was noticed that if the very first 'stealing' request failed to
create for some reason then the 'steal all ids' loop would immediately
exit with 'last' still being NULL. The test would attempt to continue
but using a null pointer. Fix that by aborting the test if it fails to
create any requests at all.
