When using a WDFDMATRANSACTION, when does the framework call
PutScatterGatherList on my behalf? Is it as soon as EvtProgramDma is
done, when WdfDmaTransactionCompleted is called or some other time?

Taking a quick look, it is called when you call WdfDmaTransactionDmaCompleted or WdfDmaTransactionRelease or the object is deleted.
