Lock scenario: Channel 1 was allocated and prepared as slave_sg, used and freed. Now preparation of cyclic dma on channel 1 will fail with err "DMA configuration conflict" because tdc->isr_handler still setted to handle_once_dma_done. This happens because tegra_dma_abort_all() won't be called on channel freeing if pending list is empty and channel not busy. We need to clear isr_handler on channel freeing to avoid locking.
