Another abort race: An io request is started, becomes active, and is attempted to be started with the lldd. At the same time the controller is stopped/torndown and an itterator is run to abort the ios. As the io is active, it is added to the outstanding aborted io count. However on the original io request thread, the driver ends up rejecting the io due to the condition that induced the controller teardown. The driver reject path didn't check whether it was in the outstanding io count. This left the count outstanding stopping controller teardown. Correct by, in the driver reject case, setting the state to inactive and checking whether it was in the outstanding io count.
