dmaengine: stm32-dma: use vchan_terminate_vdesc() in .terminate_all
[ Upstream commit d80cbef35bf89b763f06e03bb4ff8f933bf012c5 ]
To avoid race with vchan_complete, use the race free way to terminate
running transfer.
Move vdesc->node list_del in stm32_dma_start_transfer instead of in
stm32_mdma_chan_complete to avoid another race in vchan_dma_desc_free_list.
