dmaengine: sirf: fix a typo in moving running dma_desc to active queue

Browse Source 
list_move_tail(&schan->queued, &schan->active) makes the list_empty(schan->queued)
undefined, we either should change it to:
list_move_tail(schan->queued.next, &schan->active)
or
list_move_tail(&sdesc->node, &schan->active)
