dmaengine: tegra: Fix memory leak in terminate_all()

Browse Source 
Terminate vdesc when terminating an ongoing transfer.
This will ensure that the vdesc is present in the desc_terminated list
The descriptor will be freed later in desc_free_list().

This fixes the memory leaks which can happen when terminating an
ongoing transfer.
